Acyl(phenylselanyl)methylidene(triphenyl)-lambda(5)-arsanes 3 have been synthesized by treating acylmethylidene(triphenyl)-lambda(5)-arsanes 1 with phenylselanyl iodide 2; alpha-selanylarsonium ylides 3 are sufficiently reactive to undergo Wittig-type reactions, affording a novel method for the stereoselective synthesis of (Z)-alpha-phenylselanyl alpha,beta-unsaturated ketones 6.
