A process for preparing an organic silicon compound is here disclosed which comprises the step of reacting a halogenated hydrocarbon selected from the group consisting ##STR1## wherein each of X.sup.1 to X.sup.16 is selected from the group consisting of hydrogen, an alkyl group, alkenyl group, phenyl group, naphthyl group, alkoxy group, acyl group, alkylamino group and dialkylamino group having 1 to 20 carbon atoms which are unsubstituted or substituted and a halogen atom; and each of at least one of X.sup.1 to X.sup.4, at least one of X.sup.8 to X.sup.10 and at least one of X.sup.11 to X.sup.16 is a halogen atom, with a silane selected from the group consisting of SiH.sub.4, Si.sub.2 H.sub.6 and Si.sub.3 H.sub.8.

Process for preparing organic silicon compound

A process for producing silanes represented by the general formula SI.sub.n H.sub.2n+2 wherein n is 1 or 2, which comprises (a) preparing a silicon-magnesium alloy containing at least one element selected from the goup consisting of Li, Na, K, Ca, Ba, Ti, Zr, Nb, Cr, Mo, Mn, Fe, Co, Ni, Pd, Cu, Ag, Zn, Cd, Al, Sn, Pb, Bi, Se, S and C as a third component element; (b) reacting the alloy containing the third component element with an acid in an ammonia solvent; and (c) thus, varying the ratio of Si.sub.2 H.sub.6 formed to SiH.sub.4 formed.

Process for producing silanes

A process for disproportionating silanes, which comprises contacting a silane having at least one Si--H bond represented by the general formula

Process for disproportionating silanes

A process for producing silicon hydrides represented by the general formula Si.sub.n H.sub.2n+2 wherein n is a positive integer of 1 to 6, which comprises reacting a silicon-containing alloy with an aqueous solution of an acid in the presence of at least one inert organic solvent having a boiling range of from -60.degree. C. to 250.degree. C.
