hydrolysis. With molar proportions of these reagents inseparable mixtures of mono- and di-substituted compounds were obtained. The lithio-derivatives were converted into the methyl derivatives with dimethyl sulphate, and also underwent thermal elimination of LiCl to give the corresponding arynes. The title compound reacted readily with both piperidine and methoxide to give the 4- and 4,4′-substituted polychlorobiphenyls

ne to act as a template to form a pair of polymorphic cocrystals with trans-1,2-bis(4-pyridyl)ethylene is reported. After exposure to ultraviolet light, a nearly quantitative yield for the [2 + 2] cycloadditionreaction was observed for both concomitant cocrystals. These crystalline solids engage in both I···N halogen bonds along with nontraditional C–H···N hydrogen bond which results in a one-dimensional

5-tetrachloro-3-iodobenzene (C6HICl4) and each of three isosteric bipyridines is reported. Even though C6HICl4 is capable of forming both halogen and hydrogen bonds the donor is found to form co-crystals with only I⋯N halogen bonds when the initial ratio of the molecular components is 2 : 1. Molecules of C6HICl4 stack in a homogeneous and face-to-face configuration which aligns the bipyridine-based acceptor molecule
