✦ Synopsis

Transient terminal phosphinidene complexes [RP-M(CO) 5 ] (M ‫ס‬ Mo, W, R ‫ס‬ Ph, Me), as generated from the corresponding 7-phosphanorbornadiene complexes, react with N-methyl(benzylidene)amine to afford the diazaphospholane complexes 3,4 (R ‫ס‬ Ph) or a mixture of diazaphospholane 9 and 1,2,3-azadiphosphetidine 10 (R ‫ס‬ Me), probably by insertion of either one molecule of imine or one molecule of phosphinidene into the weak P-N bond of the unstable intermediate azaphosphiridine 11. The new complex 10 has been submitted to an X-ray crystal structure analysis.
