Abstract
A number of 1-(4-substituted phenyl)-2-(4-(alken-3-yl- 1)phenyl)ethynes have been synthesized by coupling of 4- substituted phenylacetylenes with new intermediates 1-(4'- iodophenyl)-alkenes-3, which were prepared by a reaction of either allylmagnesium chloride or crotylmagnesium chloride or crotylmagnesium chloride with 4-iodobenzyl bromide. The resulting compounds form mesophases - predominantly nematic - in a wide temperature range and enhance optical birefringence of nematic materials.
