标 题 :Process for synthesis of aromatic sulfides
发明人：HAY ALLAN S; WANG ZHI Y
权利人:HAY ALLAN S; WANG ZHI Y
摘要:Aromatic sulfides including diarylsulfides and poly(arylene sulfides) are produced in a novel synthesis in high yield under moderate conditions by heating an aromatic disulfide in the presence of aromatic halide, in which the halide is chloride, bromide or iodide; the diaryl sulfides are useful precursors and starting materials for a range of compounds and the poly(arylene sulfides) are important high temperature engineering thermoplastics.

摘要:Disclosed is a silyl thioalkene compound, as a class of organosilicon compounds, represented by the general formula n n R(--CSArâ•?CHSiX.sub.3).sub.n, n n in which the subscript n is 1 or 2, R is, when n is 1, a hydrogen atom or unsubstituted or substituted monovalent hydrocarbon group or, when n is 2, a divalent hydrocarbon group, Ar is an unsubstituted or nucleus-substituted aromatic monovalent aromatic hydrocarbon group and X is a halogen atom, a monovalent hydrocarbon group or hydrocarbyloxy group, having usefulness as an intermediate in the synthesis of various precision organic chemicals. The compound, of which X is a halogen atom X 1 , can be prepared, for example, by the reaction of an alkyne compound of the general formula n n R(--C.tbd.CH).sub.n, n n with a silyl sulfide compound of the general formula n n ArS--SiX.sup.1.sub.3, n n in the presence of a platinum complex catalyst. The compound, of which X is a monovalent hydrocarbon group or a hydrocarbyloxy group, can be derived from the above obtained halogen-containing compoud.
