Under pressure of 2.0MPa and at 70-75℃, the reaction of some olefins containing nitrogen with PH~3 in the presence of AIBN and C~6D~6 was studied by using the pressurized in-situ NMR technique. Experimental results indicated that the reactions of PH~3 with acrylonitrile, allylamine, 4-vinylpyridine and N-vinylcarbozole could offord corresponding tertiary organophosphorous compounds, but aminopyrin did not react with PH~3 and the reaction of acrylamide with PH~3 offored only a small amount of organic phosphino-compound. The reaction might be a better route to organo-phosphorous compounds.
