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.
