Abstract

The preparations of cis-2,4,5-triaryl-4,5-dihydro-1H-imidazoles, (aryl = thien-2-yl or pyridin-2-yl) from aryl aldehydes, ammonium chloride and triethylamine in methanol, and their conversions to the trans-isomers are reported. Crystal structures of cis-(1: aryl=pyridin-2-yl), cis-[1: aryl=thien-2-yl.0.5H(2)O], trans-(1: aryl=thien-2-yl), and trans-{[(1: aryl=pyridin-2-yl)H](+)[OAc](-) center dot 3H(2)O), have been determined and compared with related structures.
