Patent ID: 8410301

Claim:
A method for the preparation of an organic sulfide compound of formula 1 comprising, reacting a nucleophile of formula 3 and an organic sulfur-indium complex of formula 2 to form the organic sulfide compound of formula 1, wherein in formula 1 R 1 is derived from the nucleophile of formula 3 and R is derived from the organic sulfur-indium complex of formula 2, R 1 (SR) n formula 1 In(SR) 3 formula 2 R 1 —X m formula 3 wherein m is 1 or 2; when m is 1, R 1 is 1-naphthyl, 2-napthyhyl, 3-ethoxycargonylphenyl, 2-styryl, or ethoxycarbonyl-1-cyclohexane-2-yl, and n is 1; and when m is 2, R 1 is and n is 2; R is a phenyl or a linear or branched alkyl group of 1 to 6 carbon atoms; and X is Cl, Br, I, —OSO 2 CF 3 , —OSO 3 CH 3 , —OC 4 H 6 CH 3 iodonium of formula RI 4 PhBF 4 − or RI 4 Br − , wherein R is Ph, 2-thienyl, 4-methoxyphenyl, or trans-beta-styryl, or an azonium salt of formula —N 2 + X − , wherein X is Cl, Br, or I.
