Organotinchlorides of the general formula R3SnCl and R2SnCl2 (R = Me, n-Bu, Ph) can easily be converted into the corresponding hydrides R3SiH and R2SiH2 employing NaH in diethylene glycol dialkyl ethers.Using trialkyltinhydrides like Bu3SnH in combination with a catalyst (tertiary amines, N-heterocycles, phosphonium or ammonium salts), Si-Cl bonds in mono- and disilanes are hydrogenated.In the case of disilanes, Si-Si bond cleavage and concurrent hydrogenation can be afforded with strongly nucleophilic catalysts.Partial hydrogenation is also possible.The whole process can be run cyclically. - Keywords: Alkylstannylhydride; Hydrogenation; Organochlorsilane.
