Generation of Azomethine Ylides via the Desilylation Reaction of Immonium Salts
Generation of intermediates having azomethine ylide reactivity was achieved by the reaction of several ethanol or thioimidate derivatives with methyl iodide followed by treatment of the resulting imine with (trimethylsilyl)methyl triflate.Desilylation of

Addition de cyano-2 aziridines a quelques alcynes; obtention de pyrroles
Addition of the α-bromocinnamonitrile to primary amines (Cromwell method) leads to 2-cyano-3-phenyl-N-alkyl-aziridines, but the formation of the isomeric enamines always competes with this reaction.These aziridines, which are potential azomethine-ylids, a
