Reaction Steps

Utilizing the procedure of Example 1, this compound is prepared from 17.7 grams (0.1 mole) of dichlorophenylsilane, 42.5 grams (0.1 mole) of 2,2'-methylenebis(4,6-di-t-butylphenol) and 20.2 grams (0.20 mole) of triethylamine. Recrystallization twice from acetonitrile-toluene yields 34.0 grams (64% yield) of product as an off white powder, mp 153°-156° C.; IR: 2200 cm-1SiH.
