Product 1

HCID 114552Dichloro(methyl)(2-phenylpropyl)silane

Procedure

The process described in Example 2 is repeated, except that 1.3 liters of methyldichlorosilane, 1.7 liters of 1-methylstyrene and 5 ml of the catalytic solution are substituted for the trichlorosilane, allyl chloride and catalytic solution and the process is carried out at a temperature of 140° C. instead of 120° C. About 97.9 mol percent of the methyldichlorosilane used is converted and 12.8 moles per hour of 2-phenyl-2-methylethyl (methyl) dichlorosilane are obtained having a purity of 97.2 percent by weight as determined by gas chromatography.

Workup

  1. customis carried out at a temperature of 140° C. instead of 120° C
