摘要：

Alkenes may be synthesised from (alpha-bromobenzyl)benzyldiphenylphosphonium salts by the action of amine bases. A series of stilbenes was synthesised by the action of N-bromosuccinimide and 2,2,6,6-tetramethylpiperidine directly upon dibenzyldiphenylphosphonium salts. The reaction, essentially a phosphonium analogue of the Ramberg Backlund displays a similar level of cis selectivity as that shown by the parent sulfone.
