Reactions of 4-methyl- and 4,6-dimethylresorcinols with (2-ethoxyvinyl)phosphonic dichloride – synthesis of new regioisomeric cage phosphonates

Abstract

Regioisomeric cage phosphonates have been prepared and isolated for the first time by the reaction of 4-methyl- and 4,6-dimethylresorcinols with (2-ethoxyvinyl)phosphonic dichloride. It has been shown that different phosphorus-containing heterocyclic compounds are formed depending on the nature of substituent at positions 4 and 6 of resorcinol aromatic ring.
