title: Cadmium iodide mediated allenylation of terminal alkynes for the synthesis of methyl-substituted allenes.
abstract: A cadmium iodide mediated tandem reaction involving amine and two molecules of terminal alkynes for the synthesis of trisubstituted allenes has been developed. By applying this protocol, methyl-substituted allenes may be obtained easily from two molecules of terminal alkynes and pyrrolidine via methyl ketoniminium and propargylic amine formation, 1,5-hydride transfer and β-elimination.
