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

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.

By reaction of bisphosphoryl quinone methides 2 with diethyl phosphite or diphenylphosphine oxide, depending on sterical requirements, the trisphosphorylderivatives 4a and 4b or 5 and 6 respectively, are formed. The latter reaction represents a new phosph
α-SUBSTITUIERTE PHOSPHONATE 62. TRIETHOXYPHOSPHONIUM-YLIDE BZW.-BETAINE AUS TRIETHYLPHOSPHIT UND 7-PHOSPHORYL-CHINONMETHIDEN, SYNTHESE UND REAKTIVITAET

By addition of triethylphosphit (TEP) to the 7-diethylphosphono- or 7-diphenylphosphinyl-3,5-di-tert.-butyl-quinone methides 4a,b are formed by proton transfer, the surprisingly stable triethoxyphosphonium ylides 14a,b and not the expected phosphonium-bet
