A variety of α-halo organoindium reagents were prepared in situ from the reaction of gem-dihalo compounds with indium metal, and their reactions with carbonyl compounds and electron-deficient alkenes were examined. The reactions of simple 1,1-diiodoalkanes with indium metal gave no defined products but benzal iodide gave stilbene in a moderate yield. α-Halo organoindium reagents derived from α,α-dibromo carbonyl compounds gave oxiranes and cyclopropanes upon the reactions with aldehydes and alkenes, respectively. 3,3-Dichloropropenes reacted with aldehydes in the presence of indium metal to give the corresponding chlorohydrins and/or homoallylalcohols, depending on the structures of both the dichloropropenes and aldehydes employed.

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
