INTRODUCTION The reactions of the four-membered heterocyclic sulfides have not been extensively studied* That these strained rings will open is to be expected, but by analogy with the four-membered carbocyclic compounds, these rings would be expected to be more stable than those of the three- membered heterocyclic sulfides. This has been shown to be the case. Both trimethylene sulfide and B, B-dimethyl tri- methylene sulfide will form salts with mercuric chloride. 1 *2 These cyclic sulfides will also form sulfones when treated with 30 per cent hydrogen peroxide or potassium permangan- ate. 1 * 2 Three-membered cyclic sulfide rings, due to strain, suffer cleavage of the carbon-sulfur bond on perox­ ide oxidation.^ Cleavage of the carbon-sulfur bond has been accom­ plished by treating the four-membered ring sulfides with various reagents. Methyl iodide cleaves the ring at the carbon-sulfur bond^»^»^ to give, in the case of trimethylene sulfide, 3-iodopropyl dimethyl sulfonium iodide.^ It has been postulated that this cleavage proceeds throu#i an un­ stable cyclic sulfonium intermediate.^ Trimethylene sul­ fide has been reported to polymerize in the presence of nitric acid and hydrochloric acids.The ring has also Reproduced with permission of the copyright owner.

Bost and Conn^ reported that trimethylene sulfide forms an addition compound with bromine which was, however, unstable, decom­ posing even at -15®. They failed to identify the decomposi­ tion products. Reproduced with permission of the copyright owner. Further reproduction prohibited without permission. CHAPTER I DISCUSSION OF THE WORK The 3-membered sulfide ring in propylene sulfide is opened by such oxidizing agents as 30 per cent hydrogen per­ oxide, nitric acid, and the halogens, chlorine and bromine. With the halogens the nature of the cleavage products ob­ tained varied with the solvent u s e d . ^*7 aqueous chlorine l-chloro-propane-2-sulfonyl chloride was formed. Addition of chlorine or bromine to propylene sulfide in anhydrous solvents gave quantitative yields of bis-(l-methyl-2 -halo- ethyl) disulfides. With 30 per cent hydrogen peroxide, in addition to a primary cleavage and oxidation product, 2 - hydroxypropane-l-sulfonic acid, sulfuric acid was formed by the complete cleavage and oxidation of the sulfur atom. In this work the oxidation of trimethylene sulfide by these same oxidizing agents has been studied. As with propylene sulfide, the reaction of halogens produces dif­ ferent types of products in aqueoud and non-aqueous solu­ tion. When a calculated molar equivalent of chlorine was passed into a chloroform solution of trimethylene sulfide, bis-(3*chloropropyl)disulfide (I.) was produced in accord­ ance with the following equation: CHgCHgCHg + Clg — ^ClCHgCHgCHgSSGHjCHgCHjCl (I.) Reproduced with permission of the copyright owner. Further reproduction prohibited without permission. Sulfur analysis on (I) substantiates the structure shown. Treatment of (I) with excess piperidine, followed by an­ hydrous hydrogen chloride yieldéd a solid derivative, bis- (3-piperidlnopropyl)disulfide dihydrochloride, (II) then (CICH2 CH2 CH2 S2 -h 4 C5 H10N HCl-- CcH-iQWCHoCHjChjS ^ I-2KC1 -b 2 C H NH.HCl C5 H1QNCK2 CH2 CH2 S (II) Similarly trimethylene sulfide reacted readily with a molar equivalent of bromine to give an addition product which, however, was unstable to heating and could not be distilled without decomposition. The crude product was shown to be bis-(3-bromopropyl)disulfide by converting it to a solid derivative identical with (II) on treatment with piperidine followed by hydrogen chloride. Sulfur analysis on a sample of the crude bromine addition product, though not in close agreement with the calculated value, also sub­ stantiates the structure given. Three-chloropropane-l-sulfenyl chloride(III) has been prepared by the addition of a chloroform solution of trimethylene sulfide to liquid chlorine, reversing the order of addition described above. This reacts with tri­ methylene sulfide to give (I).^ Hence, the sulfenyl halide is probably an intermediate in the reaction in which the halogen is added to the sulfide. A probable mechanism for addition of halogen to trimethylene sulfide may be as fol­ lows: Reproduced with permission of the copyright owner. Further reproduction prohibited without permission.

In View of the rea<V' con'Vereion of aroma.tie hydrocarbons into solid s-ulfonyl chloride deri.Yatives by chloro.eulfonic acid~ it seemed profitable to extend the reaction to include aromatic halides.

The reaction of substituted propargylamines and homopropargylic alcohols with the in situ generated low-valent niobium complex (based on the reaction of NbCl5 with magnesium metal) is an efficient tool for the synthesis of allylamines and homoallylic alcohols bearing a 1,2-disubstituted double bond. It was found that the well-known approach for the reduction of alkynes based on the use of the TaCl5-Mg reagent system does not work for 2-alkynylamines and 3-alkynylols. Thus, this article reveals a difference in the behavior of two reagent systems—NbCl5-Mg and TaCl5-Mg, Citation: Kadikova, R.N.; Gabdullin, in relation to oxygen- and nitrogen-containing alkynes.

Title STUDIES ON THE MECHANISM OF THE ALKALINE HY- DROLYSIS OF THIOLSULFINATES Redacted for Privacy Abstract approved c (Major professor) í- The alkaline hydrolysis of phenylbenzenethiolsulfinate was studied at various pHs in an aqueous solution of 25% dioxane. A pH stat was constructed to follow the rate of disappearance of hydroxide ion under pseudo- first -order conditions. Comparative studies were made under identical conditions by following the disappearance of the thiolsulfin- ate in a buffered solution in the ultraviolet at 296 m,t(. A product study was made which indicates that the reaction fol- lows the course indicated in Equation 1. 3(pSóS() + 20H 2COSS1) + 20S02 + H2O (Eq. 1) The kinetic studies indicate that the reaction does not follow simple first -order kinetics but is quite complex. The first -order plots exhibit a marked curvature, being fast initially and slowing to a final lesser first -order rate. Possible schemes are discussed which can explain this curvature but no mechanistic conclusions are dr awn. The extreme complexity of the data suggests that the glass elec- trode response is altered by the presence of the dioxane to such a degree as to render it unreliable as a mechanistic tool. For this reason, it is suggested that further studies on the mechanism of the reaction be carried out in purely aqueous media. To this end the synthesis of a sufficiently water - soluble thiolsulfinate was attempted. The results of this work indicate that the alkaline hydrolysis of thiolsulfinates is a complex and very facile reaction, requiring study in several systems to fully elucidate its mechanism.

  • The Synthesis of Anthranilic Acid, Tryptophan, and Sulfenyl Chloride Analogues, and Enzymatic Studies
    THE SYNTHESIS OF ANTHRANILIC ACID, TRYPTOPHAN, AND SULFENYL CHLORIDE ANALOGUES, AND ENZYMATIC STUDIES By Phanneth Som (Under the Direction of ROBERT S. PHILLIPS) Abstract This dissertation includes four chapters. Chapter 1 includes the introduction and literature review. Chapter 2 covers the enzymatic synthesis of tryptophan via anthranilic acid analogues. Chapter 3 covers the nitration and resolution of tryptophan and synthesis of tryptophan derivatives. Chapter 4 covers the synthesis of sulfenyl chloride derivatives. Tryptophan is important in many aspects in the studies of proteins and also serves as precursors for important compounds. The enzymatic synthesis of tryptophan analogues from anthranilic acid analogues is important and could provide a more efficient route for incorporation of non-canonical amino acids onto proteins. Nitration of tryptophan is also important because it provides a synthetic route for synthesizing other derivatives of tryptophan. Sulfenyl chloride derivatives can be used for labeling proteins and the tryptophan analogues can be determined by mass spectrometry analysis with proteins with a limited number of tryptophan residues makes this application useful.

Abstract There is a great need in the chemical industry for developing CO2 as a C1 building block as an important step towards “green chemistry”. CO2 is also attractive as a chemical feedstock because it is readily available, inexpensive, nontoxic and it can replace toxic building blocks such as phosgene and CO.
