Abstract:
1. A process for preparing a hydridosilane, the process comprising: a) reacting at least one halosilane of formula: Si b) hydrogenating the at least one halosilane of formula: Si c) separating the hydridosilane of formula: Si d) optionally, hydrogenating the partially halogenated hydridosilanes of formula: to form at least one hydridosilane, wherein: n is greater than or equal to 3; X independently represents F, Cl, Br, I, or a mixture thereof; a represents 0 or 1; b represents 0 or 1; c represents 0 or 1; Y represents R, R′ and/or R″ independently represent —C when c=0, two or three of R, R′ and R″ together form a cyclic or bicyclic, heteroaliphatic or heteroaromatic system including N, with the proviso that at least one R, R′ or R″ radical is not —CH when c=1, R and R′ and/or R″ are each —C when a=b=c=0, R′″; R′″ represents —C m is greater than n; and 1<y<2 m+1).
