Yield:1631-84-1 84.7% ，994-30-9 97.5%

Reaction Conditions:

with tetra-n-butylphosphonium chloride at 100 - 120; for 3 h;Inert atmosphere;

Steps:

1 Production of phenyldichlorosilane

A reflux condenser, a thermometer and a stirrer are attached to a 500 mL four-necked glass flask, and the inside is installed. Was replaced with nitrogen. In this flask, 211.5 g (1.0 mol) of phenyltrichlorosilane ) And 5.9 g (0.02 mol) of tetrabutylphosphonium chloride. Internal temperature 69.0 g (0.6 mol) of triethylsilane for 2 hours while adjusting the temperature to 100-120 ° C. After hanging and dropping, it was aged at the same temperature for 1 hour. Internal temperature of the obtained reaction solution under reduced pressure The reaction mixture was allowed to flow out and separated from the catalyst while adjusting so that the temperature did not exceed 90 ° C. Gain By rectifying the obtained fraction, 90.3 g of phenyldichlorosilane (0.508 mo) Yield 84.7% with respect to triethylsilane) and 88.2 g of triethylchlorosilane (0.585 mol, yield 97.5% based on triethylsilane) was obtained.
