[1,2,3]Triazolo[4,5-d][1,3,2]thiazaphospholes: a new fused NPS ring system from a cycloaddition–rearrangement sequence with Lawesson’s reagent, a super dipolarophile
Abstract
A new fused NPS ring system has been obtained from the reaction of substituted 1,2,3-triazolium-1-imide 1,3-dipoles with Lawesson’s reagent
