Abstract

Abstract On the basis of the reaction of ethynediylbisphosphonates and chloroethynylphosphonates with classical donor alka-1, 3-dienes, a general strategy for synthesis of o-bisphosphanylbenzenes and o-chlorophosphanylbenzenes, which includes two consecutive steps: Diels-Alder condensation→ aromatization of the carbocyclic phosphonate (bisphosphonate) formed→ reduction of the phosphonate groups, was ...
