Participants

Reaction Conditions

Reaction Steps

52.5 g (0.3 mol) of 2-chlorobenzoyl chloride were warmed to 80° C. under a nitrogen atmosphere. 69 g (0.3 mol) of 6-methoxy-(6H)-dibenz[c,e][1,2]oxaphosphorin were added dropwise while stirring. During the dropwise addition, the mixture was cooled to 60° C., and the temperature was then kept at 60°-70° C. When the reaction was complete, 40 ml of toluene were added at 45° C. 92 g (89% of theory) of the abovementioned compound of melting point 108° to 110° C. were obtained.
