Under the following reaction conditions: temperature 50~70癈, pressure 1.0~2.0 MPa, solvent C6D6, initiator AIBN, the reactions of 1,4-pentadiene, 1,7-octadiene and 1-decaoctene with PH3 were studied by using the pressurized in-situ NMR technique. Experimental results indicated that the six-membered phosphorinane is formed by the addition pf PH3 to 1,4-pentadiene, phosphonane can't be obtained by 1,7-octadiene, and primary phosphine is the predominant product in the reaction of PH3 with 1-decaoctene. The results obtained by in-situ 31P NMR spectra also indicated that the reactions of PH3 with linear olefins proceed with a sequential mechanism.
