Abstract
3,6-Dichloropyridazine was ortho-lithiated by lithium 2,2,6,6-tetramethylpiperidide. The resulting lithio compound was reacted with carbonyl derivatives iodine and trimethylchlorosilane. An azaxanthone was synthesised. An unusual regioselectivity for the lithiation of 2,4-dichloropyrimidine was studied.
