| Abstract: | The first phosphazide and monosubstituted triazenide complexes have been prepared by allowing either phenyl or p-tolylazide to react with WBr2 (CO)3(PPh3)2 and WH(CO)2(NO) (PPh3)2 under mild conditions to yield WBr2 (CO)3(RN3PPh3) and W(RN3H) (CO) (NO) (PPh3)2, respectively. The same arly azides react with W(CO)2 (S2CNEt2)2)(PPh3) to yield dinitrogen and the aryl nitrene complex, W(CO) (RN) (S2CNEt2)2. The coordinated RN3PR3 and RN3H3 are of special interest because they may aid understanding the mechanism of nitrene and amide formation from azides. |
