Zusammenfassung

The reaction of the phosphinidene complex [Cp*P{W(CO)(5)}(2)] (1a) with diphenyldiazomethane leads to [{W(CO)(5)}Cp*P=NN{W(CO)(5)}=CPh2] (2). Compound 2 is a rare example of a phosphadiazadiene ligand (R-P=N-N=CRR) complex. At temperatures above 0 degrees C, 2 decomposes into the complex [{W(CO)(5)}PCp*{N(H)N=CPh2)(2)] (3), among other species. The reaction of the pentelidene complexes ...
