P, P, P -trihalobenzo-1,3,2-dioxaphopholes in the reaction with aliphatic acetylenes and diacetylenes: Synthesis of new phosphacoumarins

Abstract

Bis(benzo[e]-1,2-oxaphosphinin-2-oxid-4(7)-yl)butane (-benzene) derivatives were synthesized for the first time both on the basis of reactions of diacetylene with P,P, P-trihalobenzo-1,3,2-dioxaphopholes and on the basis of reactions of bis(P,P,P-trihalobenzo-1,3,2-dioxaphosphol-5-yl)bytane (-benzene) with phenylacetylene. © 2013 Copyright Taylor and Francis Group, LLC.
