Abstract
The properties and reactions of complexes of the type [(π-C5H5)M(CO)2N:CRR′](M = Mo, W; R = Ph, R′= But) closely resemble those of the di-t-butyl rather than the diphenyl derivatives. Complexes of the type [(π-C5H5M(CO)N:CButPh]2 and [(π-C5H5)M(CO)2(PhButPh)] were not formed. With triphenylphosphine, the Mo complex formed a substitution product [(π-C5H5)Mo(CO)(PPh3)N:CButPh], in contrast to all other methyleneamino-complexes studied. With iodine, substitution analogous to that of the di-t-butyl complex, resulted in the formation of [(π-C5H5)M(CO)I2N:CButPh]. The reaction of PhButC:NSiMe3 with [(π-C5H5)Mo(CO)3Cl] in monoglyme gave [(π-C5H5)Mo(CO)2(HN:CButPh)Cl].Keywords
