実験手順
60.1 g (0.3 mol) of 2,6-dimethoxybenzoyl chloride were warmed to 85° 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. The temperature was then slowly increased to 125° C. When the reaction was complete and after cooling, 150 ml of toluene were added. After crystallization, 99 g (87% of theory) of the abovementioned compound of melting point 96° to 98° C. were obtained.
