Ethyl α-phenylseleno-α,β-unsaturated esters were prepared by the reaction of tri-ethyl phosphonoacetate anion and ethoxycarbonyl(phenylselenenyl)methylidene(triphenyl)phosphorane with aliphatic and aromatic aldehydes. The α-phenylseleno unsaturated esters

α-Hypervalent iodine functionalized phosphonium and arsonium ylides 2 can be used as umpolung ylides to react with nucleophiles to give α-heteroatom substituted ylides 4 in good yields. The nucleophilic substitution - Wittig tandem reaction of 2 can occur smoothly to provide an efficient method for the synthesis of (Z)-α-halo-α,β-unsaturated enoates or enones 6, stereoselectively.
Tandem reaction of α-hypervalent iodo functionalized phosphonium and arsonium ylides as umpolung reagents
