Despite the apparent lower efficiency of iron-based catalysts, their use is of interest due to the comparative cost advantage of iron compared to the other metals commonly employed as catalysts for these reactions. Since little is known about the mec

The trioxo anions [Cp*W(O)[sub 3]][sup [minus]] and [Cp*Mo(O)[sub 3]][sup [minus]] have been shown to be useful reagents for the formation of [mu]-oxo complexes via halide displacement reactions. For example, they react with Cp*M(O)[sub 2]Cl (M = Mo,

The cationic alkylidyne complexes [Cp(CO)[sub 2]M=VCCH[sub 2]R][sup +] (M = Re, R = H; M = Mn, R = H, Me, Ph) undergo facile deprotonation to give the corresponding neutral vinylidene complexes Cp(CO)[sub 2]M=C=C(H)R. For [Cp(CO)[sub 2]Re=VCCH[sub 3]

Both Cp*WCl[sub 4] and Cp*MoCL[sub 4] react with aqueous Bu[sup t]NH[sub 2] in the presence of air to form the trioxo anions [Cp*M(O)[sub 3]][sup [minus]], which have been isolated as their [Bu[sup t]NH[sub 3]][sup +] salts. The trioxo anions are als

The BPh[sub 4][sup [minus]] salt of the carbyne complex [Cp(CO)[sub 2]Re[equivalent to]CTol][sup +], 1, undergoes net [2 + 2] cycloaddition of cis-azobenzene, cis-axotoluene, and benzo [c] cinnoline to give new complexes 5a, 5b, and 7, respectively,
