    摘要: The invention relates to a method for producing hydridosilanes from halosilanes by a) reacting i) at least one halosilane of the generic formula SinX2n+2 (with n≧3 and X═F, Cl, Br and/or I) with ii) at least one catalyst of the generic formula NRR'aR″bYc with a=0 or 1, b=0 or 1, and c=0 or 1, and formula (I), wherein aa) R, R′ and/or R″ are —C1-C12 alkyl, —C1-C12 aryl, —C1-C12 aralkyl, —C1-C12 aminoalkyl, —C1-C12 aminoaryl, —C1-C12 aminoaralkyl, 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 —CH3 and/or wherein bb) R and R′ and/or R″' (if c=1) are —C1-C12 alkylene, —C1-C12 arylene, —C1-C12 aralkylene, —C1-C12 heteroalkylene, —C1-C12 heteroarylene, —C1-C12 heteroaralkylene and/or —N═, or cc) (if a=b=c=0) R═≡C-R′″ (with R′″═—C1-C10 alkyl, —C1-C10 aryl and/or —C1-C10 aralkyl), while forming a mixture comprising at least one halosilane of the generic formula SimX2m+2 (with m>n and X═F, Cl, Br and/or I) and SiX4 (with X═F, Cl, Br and/or I), and b) hydrogenating the at least one halosilane of the generic formula SimH2m+2 while forming a hydridosilane of the generic formula SimH2m+2. The invention also relates to the hydridosilanes producible according to said method and to their use.
