Synthesis of Stilbenes Promoted by the Mixture of Zinc and Iron Powder

Abstract

Stilbenes have been synthesised by a one-pot reaction of aldehydes with benzyl bromide. The reaction was promoted by both triphenylphosphine and the mixture of zinc and iron together in sealed tube. The yields ranged from moderate to excellent.

Zinc-Mediated Facile Synthesis of α,β-Unsaturated Primary Amides

“…11 However, in many cases these methods were of limited scope. The Wittig reaction 12 is one of the most important general methods for the construction of carbon-carbon double bonds, and as a part of our studies on developing new Wittig reactions, [13][14][15][16] we considered developing a general route to α,β-unsaturated primary amide via a Wittig method.…”
