专利号:US-5233069-A 优先权日:1991-12-24 标题:Bis(silyl)methanes and their direct synthesis 发明人:JUNG IL N; YEON SEUNG H; HAN JOON S 权利人:KOREA INST SCI & TECH 摘要:The present invention relates to bis(silyl)methanes and their preparation methods in high hields by directly reacting α-chloromethylsilanes represented by formula I incorporated with hydrogen chloride or alkylchlorides represented by the general formula II, with silicon metal to give the bis(silyl)methane compound having dichlorosily group (formula III) as the major products and the bis(silyl)methane compounds having trichlorosilyl group (formula IV) in moderately high yields in the presence of copper catalyst at a temperature from 250° C. to 350° C. The different major product is obtained depending upon the chloride incorporated. n-Butyl chloride, t-butyl chloride, propyl chloride, and hydrogen chloride gave bissilylmethane with hydrogen substituted on the silicon atom as the major product. When 1,2-dichloroethane is incorporated, bis(silyl)methanes having trichlorosilyl group is the major product. ##STR1## In formulae (I), (III), (IV), R 1 , R 2 , and R 3 are independently methyl group or chlorine atome; and R is hydrogen, alkyl(C 1 -C 4 ), CH 2 CH 2 Cl.
