Various borohydrides were found to catalyze the redistribution reaction of hydrosilane and chlorosilane in different solvents to produce hydrochlorosilanes efficiently and facilely. The redistribution reaction was affected by solvent and catalyst. The substrate scope was investigated in HMPA with LiBH4 as catalyst. A possible mechanism was proposed to explain the redistribution process.

Various alkali metal halides were found to catalyze the Si-H/Si-Cl redistribution reaction in different polar solvents efficiently. The scope of silane substrate was studied using KF as catalyst and 18-crown-6 as cocatalyst in DMI. The alkali metal halides catalyzed redistribution system provides a useful method to prepare hydrochlorosilanes more facilely. A possible mechanism was proposed to explain
