Halogen-substituted silicon compounds are hydrogenated by reaction with hydrogen in a chloroaluminate salt melt as a reaction medium containing a finely divided metal capable of forming interstitial hydrides which are suspended in the melt, the finely divided interstitial metal hydrides being formed in situ in the melt by reduction of a metal halide with an electropositive element as a halogen acceptor I selected from the group consisting of magnesium, calcium and aluminum.

Method for hydrogenating halogen-substituted silicon compounds

Gallium-alkyl compounds are produced, in that gallium-halogen compounds are reacted with alkyl aluminum halogenides in the presence of metal halogenides as auxiliary bases. Preference is given to the use of the corresponding chlorides and to the chlorides of the metals of groups I to III of the periodical table as auxiliary bases.

Process for the production of gallium-alkyl compounds

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