Facile synthesis of acetylene-substituted terthiophenes

Abstract
A modified Horner-Emmons condensation reaction was employed for the synthesis of acetylene-substituted terthiophenes in excellent yields. Conjugating 3'-aryl substituents to terthiophene using an ethyne rather than an ethene linker results in enhanced planarity of the resulting mol. as established by x-ray structural anal. of (2,2':5',2''-terthiophen-3'-yl)pyridin-4-ylethyne (data deposited with the CCDC).
