摘要

Wittig, Tochtermann and others 1 observed that some bulky borane/phosphane pairs (and related systems) are hindered toward the usual Lewis acid /Lewis base neutralization reaction. Tochtermann called such systems “antagonistische Paare”. They were used eg in the addition reaction to benzyne to yield ortho-phenylene-bridged zwitterionic phosphonium /borate compounds. Much later Stephan et al. observed that “frustrated” borane/phosphane Lewis pairs, whose direct interaction ...
