摘要

Abstract: Second order rate constants for the reactions of carboxonium ions Ar (MeO) CH+ and aldehyde-boron trihalide complexes ArCH= O-BX3 with allylsilanes and alkenes have been determined in CH2C12 solution. The relative reactivities of these electrophiles are almost independent of the nature of the n-nucleophiles, and it is possible to give an averaged reactivity order. For the electrophiles PhCH= O-BS, PhCH= O-BCh Ph@- ...
