Procedure
50 g (0.262 mol) of 1-naphthoyl chloride were warmed to 80° to 85° C. under a nitrogen atmosphere. 60.3 g (0.262 mol) of 6-methoxy-(6H)-dibenz[c,e][1,2]oxaphosphorin were added dropwise while stirring. The reaction proceeded exothermically. The temperature was then increased in steps to 125° C. When the reaction was complete, 90 ml of toluene were added at 40° C. After crystallization 77 g (80% of theory) of the abovementioned compound of melting point 149° to 151° C. were obtained.
