Abstract

Abstract The reaction of the monomethylsilane (8a) with two equivalents of the 4- (carboalkoxy)-2, 6-di-t-butyl-substituted phenol (7b) in toulene using triethylamine as an acid acceptor gave the bis (aryloxy) adduct (9a). The analogus reaction of the dimethylsilane (8b) with sodium 2, 6-di-t-butyl-4-(methoxycarboxyl)-phenolate (7a) gave only the monosubstitution product (10a). The reaction of the corresponding phenolate (7e) with 8b ...
