HCID 13244761HCID 13244761, compoundYield 79%

Procedure

Utilizing the procedure of Example 1, this compound is prepared from 25.8 grams (0.20 mole) of dichlorodimethylsilane, 87.7 grams (0.20 mole) of 2,2'-ethylidene-bis(4,6-di-t-butylphenol) and 40.5 grams (0.40 mole) of triethylamine. Recrystallization from acetonitrile-toluene yields 77.7 g (79% yield) of product as white needles, mp 171°-177° C.
