Reaction Steps

In a flame-dried flask equiped with a dry ice-acetone filled Dewar condenser and a sintered glass inlet, 42.5 grams (0.1 mole) 2,2'-methylene-bis(4,6-di-t-butylphenol) and 20.2 grams (0.2 mole) triethylamine dissolved in 100 ml tetrahydrofuran are treated slowly with 11.1 grams (0.11 mole) dichlorosilane. Filtration and recrystallization from acetonitrile-toluene gave 25.9 grams (57% yield) of a white solid mp 189°-192° C. The 1H NMR spectrum is consistent with the product.
