【発明の名称】ビスシリルメタンの製造方法
Document Type and Number:
Japanese Patent JP2837598
Kind Code:
B2
Abstract:
The present invention relates to bis(silyl)methanes and their preparation methods in high hields by directly reacting alpha -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 DEG C. to 350 DEG 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. (I) RCl (II) (III) (IV) In formulae (I), (III), (IV), R1, R2, and R3 are independently methyl group or chlorine atome; and R is hydrogen, alkyl(C1-C4), CH2CH2Cl.
