Abstract

A nicked reaction: The title reaction of terminal alkynes with non-activated secondary alkyl iodides and bromides was accomplished for the first time. This reaction provides a new and practical approach for the synthesis of substituted alkynes (see scheme; cod=cyclo-1,5-octadiene). Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
