Abstract
The invention relates to a method for producing hydridosilanes from halosilanes by a) reacting i) at least one halosilane of the generic formula SiX(with n≧3 and X═F, Cl, Br and/or I) with ii) at least one catalyst of the generic formula NRR'R″Ywith a=0 or 1, b=0 or 1, and c=0 or 1, and formula (I), wherein aa) R, R' and/or R″ are —C-Calkyl, —C-Caryl, —C-Caralkyl, —C-Caminoalkyl, —C-Caminoaryl, —C-Caminoaralkyl, and/or two or three groups R, R′ and R″ (if c=0) together form a cyclic or bicyclic, heteroaliphatic or heteroaromatic system including N, with the proviso that at least one group R, R′ or R″ is unequal —CHand/or wherein bb) R and R′ and/or R″' (if c=1) are —C-Calkylene, —C-Carylene, —C-Caralkylene, —C-Cheteroalkylene, —C-Cheteroarylene, —C-Cheteroaralkylene and/or —N═, or cc) (if a=b=c=0) R═≡C-R′″ (with R′″═—C-Calkyl, —C-Caryl and/or —C-Caralkyl), while forming a mixture comprising at least one halosilane of the generic formula SiX(with m>n and X═F, Cl, Br and/or I) and SiX(with X═F, Cl, Br and/or I), and b) hydrogenating the at least one halosilane of the generic formula SiHwhile forming a hydridosilane of the generic formula SiH. The invention also relates to the hydridosilanes producible according to said method and to their use.
