Abstract
Abstract Some reactions of pentachloropyridine with organometallic compounds have been described. n-Butyl-, methyl-, phenyl- and triphenylsilyllithium are found to react, mainly by metathesis. The Grignard reagents, like benzylmagnesium chloride and ethylmagnesium bromide give coupling products with pentachloropyridine, at the 4-position. Phenylmagnesium bromide, methylmagnesium iodide and pentafluorophenyllithium did not react with pentachloropyridine. 4,4′-Octachlorobipyridine has been synthesized by three different methods. In the reaction of 4-(trimethylsilyl) tetrachloropyridine with n-butyllithium, the existence of the short-lived 2,3-pyridyne seems probable.
