Reaction Conditions

Reaction Steps

33.7 g (0.2 mol) of 2,4-dimethylbenzoyl 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 were added dropwise with stirring. The batch began to crystallize even during the addition. The temperature when then slowly increased to 135° C. with the proviso that toluene was added as diluent at 90° C. After digestion with toluene, 58 g (83% of theory) of the abovementioned compound of melting point 166° C. were obtained from the crystallizate.
