reactions of organo-metal compounds reactions of organo-metal compounds O 0350 -090Selective α-Stannylated Addition of Di-n-butyliodotin Hydride Ate Complex to Simple Aliphatic Alkynes.-Selective α-stannylation of simple aliphatic alkynes is achieved by a novel intermediately formed tin hydride complex [MgBr] + [Bu 2 SnBrHI] − . For alkynes with large secondary and tertiary substituents (Ie) and (If), the α-alkylation is disturbed. -(SHIBATA,
