Indium(III) Chloride – Catalyzed Michael Addition of Thiols to Chalcones : a Remarkable Solvent Effect

Ranu,* Suvendu S. Dey, and Sampak Samanta Department of Organic Chemistry, Indian Association for the Cultivation of Science, Jadavpur, Calcutta – 700 032, India E-mail: [email protected] Dedicated to Dr. A. V. Rama Rao on the occasion of his 70th birthday (received 28 Aug 04; accepted 23 Sep 04; published on the web 26 Sep 04) Abstract Indium(III) chloride in methanol efficiently catalyzes Michael addition of aromatic and aliphatic thiols to chalcones and related compounds. This reaction is remarkably solvent selective and it does not proceed in conventional solvents such as tetrahydrofuran, methylene chloride and water. Keywords: Michael addition, thiol, chalcone, indium(III) chloride, solvent effect Introduction The Michael addition of thiols to electron deficient alkenes is a very useful process for making carbon-sulfur bond. This addition to chalcone derivatives is very interesting and challenging as it is less facile compared to the addition to aliphatic acyclic enones and thus it is not always satisfactory with the conventional reagents used for general 1,4-addition. Recently, a number of 1a procedures involving a variety of catalysts such as synthetic diphosphate Na2CaP2O7, natural 1b 1c 1d phosphate, InBr3, fluorapatite, have been reported. Indium halides, particularly indium(III) chloride have emerged as a potent Lewis acid for various organic transformations in recent times.2 As a part of our interest in indium(III) chloride 3 catalyzed reactions we discovered that although InCl3 has been used in the Michael addition of silylenol ethers,4a amines,4b pyrroles4c and indoles4d to electron-deficient alkenes no report has been found demonstrating the use of InCl3 for addition of thiols to chalcones and related systems. -

Thermochemical Modelling and Experimental Validation of in Situ Indium Volatilization by Released Halides During Pyrolysis of Smartphone Displays

After the conduction of several pyrolysis experiments it was found that the indium evaporation is highly temperature-dependent. At temperatures of 750 ◦C or higher the indium concentration in the pyrolysis residue was pushed below the detection limit of 20 ppm, which proved that a complete indium volatilization by using only the halides originating from the plastic fraction of the displays is possible. A continuous analysis of the pyrolysis gas via FTIR showed that the amounts of HBr, HCl and CO increase strongly at elevated temperatures. The subsequent thermodynamic consideration by means of FactSage confirmed the synergetic effect of CO on the halogenation of indium oxide. Furthermore, HBr is predicted to be a stronger halogenation agent compared to HCl. -

A New Method of Pure 111In Production by Proton-Induced Nuclear Reactions with Enriched 112Sn 19 Consequently with Low Activity)
NUKLEONIKA 2007;52(1):17−27 ORIGINAL PAPER 111 A new method of pure In production Emil Bìták, Edward Rurarz, by proton-induced nuclear reactions Stefan Mikołajewski, with enriched 112Sn Jolanta Wojtkowska Abstract. We aimed at finding out a simple and reliable way of 111In production with the highest radionuclide purity from its grand parent 111Sb and parent 111Sn nuclei, produced by the 112Sn(p,2n)111Sb and 112Sn(p,pn)111Sn reactions, respectively. The target was a metallic 112Sn sample enriched to 84%. We have measured activation cross sections for seven reactions on an enriched 112Sn sample induced by 23.6 ± 0.8 MeV energy protons. Gamma-ray spectroscopy with 55 60 high-purity germanium detectors has been used. We also identified the activities of Co (T1/2 = 17.5 h) and Cu (T1/2 = 23.7 min) in proton beam monitoring Ni foils, induced in the natNi(p,X)55Co and natNi(p,X)60Cu reactions at 22.8 MeV proton energy. The cross sections determined for these reactions are: σ[natNi(p,X)55Co] = 36.6 ± 4 mb and σ[natNi(p,X)60Cu] = 64.4 ± 7 mb. The measured cross sections of reactions on tin isotopes are: σ[112Sn(p,n)112Sb] = 4 ± 0.8 mb; σ[112Sn(p,2n)111Sb] = 182 ± 26 mb; σ[112Sn(p,pn)111Sn] = 307 ± 35 mb; σ[114Sn(p,2n)113Sb] = 442 ± 52 mb; σ[117Sn(p,n)117Sb] = 15 ± 3 mb; σ[117Sn(p,p’γ)117mSn] = 0.37 ± 0.06 mb; σ[115Sn(p,2p)114m2In] = 0.01 ± 0.002 mb. -
