Participants

Reaction Conditions

Reaction Steps

30.8 g (0.2 mol) of 4-methylbenzoyl chloride were warmed to 80° C. under a nitrogen atmosphere. 46 g (0.2 mol) of 6-methoxy-(6H)-dibenz[c,e][1,2]-oxaphosphorin 6-oxide were added dropwise over the course of 1 hour while stirring. The temperature was then slowly increased to 110° C. When the reaction was complete, the residue slowly crystallized out at room temperature. 60 g (90% of theory) of the abovementioned compound, which, after recrystallization from toluene, had a melting point of 124 to 125% C. were obtained.
