A process is described for the hydrided of halogen-substituted compounds of the second to fourth period of Groups III to V of the periodic system, with the exception of gallium, aluminum, carbon, or nitrogen. A finely-granulated aluminum is added to a molten salt melt that consists of 50-67 molar % AlCl.sub.3 (anhydrous) and 50 to 33 molar % of sodium chloride. Then to the stirred, or by some other means dispersed suspension, hydrogen is introduced to hydrided the finely-dispersed aluminum. Thereafter the mixture is reacted with the halogen-substituted compound and the resulting hydrided compound is renewed.

A process for the dismutation of chlorosilanes is disclosed in which the latter are in the gas phase for 0.01-100 sec. at 55.degree.-100.degree. C. or in the liquid phase for 1-1000 sec. at 25.degree.-55.degree. C. conducted in the presence of a catalyst, which is either unformed or is present in the form of spherical pellets, and which consists of one of four different organopolysiloxane compounds, optionally cross-linked, which essentially carry an amino or ammonium group as a functional group.

A process for the production of disilane from monosilane, in which a gaseous mixture of monosilane and hydrogen is subjected to a plasma discharge.
