The benzylene‐linked triaminophosphanes P(C6H4‐o‐CH2NHXyl)3([A]H3) and P(CH2C6H4‐o‐NHPh)3([B]H3) react with (Me2N)3Mo≡N to afford the square‐pyramidal nitrido complexes1and2, each comprising one residual dimethylamido moiety and one uncoordinated ligand sidearm. Only the [A]‐coordinated complex1was found to eliminate the remaining dimethylamido ligand on heating. Instead of the closed‐cage molybdenum(VI) nitrido complex [A]Mo≡N, cyclometalated molybdaziridine3was isolated, as thesynalignment of the uncoordinated sidearm and nitrido ligand in1inhibits a productive cage‐closure reaction. By using [NPN]‐coordinated model complexes, analogoussynarrangements were found not only for molybdenum, but also for the related tungsten nitrido complexes and the group 5 imides. Attempts to access the closed‐cage MoVInitrido comlex [A]Mo≡N by transmetalation between [A]Sn(nBu) (9) and (tBuO)3Mo≡N led to the formation of spiro‐[4.4]‐λ5‐amidophosphorane10. These results contrast with the findings made for azatranes and methylene‐linkedexo‐P‐configured triamidophosphane complexes.
