摘　　要：Some complexs of Ag(PPh 3 ) n X( n =1,2,3;X=Cl,Br,I) were electrosynthesized using NH 4 X or I 2 in non aqueous medium, in yield >95%. The mechanism of electrochemical reaction and the effect of material ratio on the complexes have been studied. When n (PPh 3 )∶ n (NH 4 X)=3∶1, Ag(PPh 3 ) 2 X(X=Cl,Br) were obtained; when n (PPh 3 )∶ n (NH 4 I/I 2 )=1∶1, AgPPh 3 I was obtained; when n (PPh 3 )∶ n (NH 4 I)= 2∶1 or 3∶1, Ag(PPh 3 ) 3 I was obtained. This method is better than the traditional chemical synthesis.Some complexs of Ag(PPh 3 ) n X( n =1,2,3;X=Cl,Br,I) were electrosynthesized using NH 4 X or I 2 in non aqueous medium, in yield >95%.
