Pure & Appi. Chem., Vol. 49, pp.67—73. Pergamon Press, 1977. Printed in Great Britain. NON-AQJEOUS SOLVENTS FOR PREPARATION AND REACTIONS OF NITROGEN HALOGEN COMPOUNDS Jochen Jander Department of Chemistry, University of Heidelberg, D 69 Heidelberg, Germany Abstract -Theimportance of non—aqueous solvents for the chemistry of haloamines is shown in more recent reaction examples. The solvents must be low-melting because of the general temperature sensitivity of the haloamines. They may take part in the reaction (formation of CH NI •CH NH (CH )2NI, NI-,.5 NH-, and NH0I.NH-)ormay e ner (ormation of I .quinuiilidin, 2 NI •1 trithylenediamine, [I(qunuclidine),] salts pure NBr, and compounds of the type R1R2NC103 with R1 and R2 =orgnicgroup or hydrogen). INTRODUCTION Non-aqueous solvents play an important role in preparation and reactions of nitrogen halogen compounds. Due to the fact, that all haloamines are derivatives of ammonia or amines, liquid ammonia or liquid organic amines are used as solvents very often. Liquid ammonia and the lower organic amines reveal, in addition, the advantage of low melting points (liquid ammonia -78, liquid monomethylamine -93.5, liquid dimethylamine -92, liquid tn-. methylamine -12k°C); these meet the general temperature sensitivity of the nitrogen halogen compounds, especially of the pure .lorganic ones. Ammonia and amines are very seldom inert solvents; they mostly take part in the reaction planned for synthesis or conversion of the haloamine. In case a reaction of the solvent is to be avoided, one has to look for a low melting inert solvent, for example methylene chloride (m.p. -

The molecular and crystal structure of the adduct NF3·BF3 was studied computationally using density functional theory. It shows that the adduct exists in the form of a complex but is not ionic. The heats of formation in the gas and the condensed phase of the adduct are −1266.09 and −1276.37 kJ·mol−1, respectively, which indicates that it is stable under atmospheric conditions. The crystal form belongs to P 21/c space group. The calculated large band gap (Eg) of the crystal proves that it is stable. The conduction band (LUCO) is mainly contributed by the p orbital of N atom and the valence band (HOCO) from the p orbital of F atom. Keywords. Molecular; crystal; structure; property; theoretical study. 1. Introduction investigation even though there is limited information on the structure–property relationship, especially on the Molecular complexes containing boron trifluoride as a crystal structure of NF3 with BF3. -

Cationic Oligomerization of Ethylene Oxide
Polymer Journal, Vol. 15, No. 12, pp 883-889 (1983) Cationic Oligomerization of Ethylene Oxide Shiro KOBAYASHI, Takatoshi KOBAYASHI, and Takeo SAEGUSA Department of Synthetic Chemistry, Faculty of Engineering, Kyoto University, Kyoto 606, Japan (Received July 29, 1983) ABSTRACT: The oligomerization of ethylene oxide (EO) was investigated with several cationic catalysts to find a method for producing cyclic oligomers (crown ethers). The reactions were monitored by NMR spectroscopy (1 H and 19F) and gas chromatography. The composition of oligomers was found to change during the reactions, and the production of 1,4-dioxane increased at the later stage of the reactions. This indicates that the composition of oligomers is kinetically controlled. The formation of higher cyclic oligomers was favored by the addition of tetrahydro pyran or 1,4-dioxane to the system catalyzed by an oxonium salt; the maximum yield of cyclic tetramer was 16.8%. The effect of alkali metal salts was also examined. A template effect was observed to increase the amount of cyclic oligomer production.
