摘要：
Reactivity of cationic transition-metal phosphenium complexes has been investigated. Reaction of mer-[(bpy)(CO)(3)M{PN(Me)CH(2)CH(2)NMe}](+) (M = Cr, Mo, W) with X(-)(X = Me, OEt) exhibits a nucleophilic attack at the phosphenium phosphorous, whereas that with L (L = phosphine, phosphite) shows CO/L substitution. Iron phosphenium complexes, [Cp(CO)RFe-{PN(Me)CH(2)CH(2)NMe}](+) undergoes a migratory insertion of the phosphenium ligand into the Fe-alkyl bond.
