Reaction Steps

Utilizing the procedure of Example 1, this compound is prepared from 23.0 grams (0.20 mole) dichloromethylsilane, 87.7 grams (0.20 mole) 2,2'-ethylidene-bis(4,6-di-t-butylphenol) and 40.5 grams (0.40 mole) of triethylamine. Recrystallization twice from acetonitrile-toluene gives 49.0 g (51% yield) of white crystals, mp 189°-194° C.
