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.

Chlorosilanes are versatile reagents in organic synthesis and material science. A mild pathway is now reported for the quantitative conversion of hydrosilanes to silyl chlorides under visible-light irradiation using neutral eosin Y as a hydrogen-atom-transfer photocatalyst and dichloromethane as a chlorinating agent. Stepwise chlorination of di- and trihydrosilanes was achieved in a highly selective fashion assisted by continuous-flow micro-tubing reactors. The ability to access silyl radicals using photocatalytic Si?H activation promoted by eosin Y offers new perspectives for the synthesis of valuable silicon reagents in a convenient and green manner.

Paragraph 0053; 0054, (2019/07/04)
The invention discloses a preparation method of phenyl chlorosilane. The preparation method comprises the following steps: (1) adding silicon powder, a copper catalyst and a sodium-containing compoundinto a reactor; (2) introducing a silicon-copper contact body modifier to pre-treat a silicon-copper contact body at a temperature of 300-500 DEG C; (3) mixing the pretreated silicon-copper contact body with a Cu-CuO-Cu2O-CuCl quaternary copper powder catalyst, and adding the mixture into the reactor; and (4) introducing chlorobenzene, controlling the reaction temperature to be 400-700 DEG C, andcarrying out a reaction to prepare phenyl chlorosilane monomers. According to the method, the use amount of the copper catalyst is low, the conversion rate of chlorobenzene is high, selectivity of phenyl chlorosilane is good, and the yield of diphenyl dichlorosilane with relatively high economic value is high in the product, so that economical efficiency of the phenyl chlorosilane prepared by thedirect method is improved.
