摘要

Stilbene may be synthesised with Z-selectivity from (α-bromobenzyl) benzyldiphenylphosphonium bromide 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-Bäcklund displays cis selectivity. The ...
