REACTION OF PHOSPHORYLATED QUINONE METHIDES WITH TRIVALENT PHOSPHORYL COMPOUNDS

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
