Reaction of esters of PIII acids with 2,6-di-tert-butyl-4-chloromethylidenecyclohexa-2,5-dienone

A reaction of PIII acid esters with 2,6-di-tert-butyl-4-chloromethylidenecyclohexa-2,5-dienone leads to the formation of phosphorylated phosphorus ylides, 3,3’,5,5’-tetra-tert-butylstilbenequinone, and diphosphorylated sterically hindered phenols. The schemes for the formation of these products through the primary key intermediates of betaine and phosphorus ylide structures were suggested.

Study of the reaction of 4-chloromethylene-2,6-di-tert-butylcyclohexa-2,5- dien-1-one with the P(III) acids esters

The main stable products of the reactions 4-chloromethylene-2,6-di-tert- butylcyclohexa-2,5-dien-1- one with triethyl phosphite and ethyl diphenylphosphinite are the phosphorylated phosphorus ylides, 3,3′,5,5′-tetra-tert-butylstilbenequinone, and biphosph
