Abstract
Reactions of dimesitylboryl stablised carbanions with aromatic aldehydes produce erythro-intermediates, which can be trapped by trimethylsilylation or trifluoroacetylation to give products which can yield E- or Z-alkenes in good overall yields in new and controllable boron–Wittig reactions.Keywords
