The N-phenyl- and N,N-diphenylhydrazones of benzaldehyde or acetophenone are readily cyclometallated on reaction with PhCH2Mn(CO)5 to give complexes 3 of the type (OC)4MnC6H4C(R1)=NNPhR2 incorporating a five-membered MnC3N ring. The example with R1=Me, R2=H has been structurally characterised. The similar reaction with the N,N-diphenylhydrazone of cyclohexanone produces a species with an alternative MnC2N2 ring which was also structurally characterised. A related species (OC)4MnC6H4NN=O is formed from N-nitrosodiphenylamine. Reactions of compounds 3 from the diphenylhydrazones with alkynes PhCCPh or Me3SiCCH give N′-indenyl-N,N-diphenylhydrazines in reasonable yields.
