摘要

Phosphazene bases 2 developed by Schwesinger and proazaphosphatranes 3 developed by Verkade are known as strong non-metallic organic superbases (Fig. 1). Among them, t-Bu-P4 base shows extremely high basicity and has been used for various selective deprotonative transformations. 4 The strong affinity of t-Bu-P4 base to protons is regarded as synthetically useful, however the ability of t-Bu-P4 base to activate α-silylalkyl compounds has not ...
