Methylene, oxygen, and sulphur addition to a µ-alkylidyne ligand in an iron–molybdenum complex: X-ray crystal structures of [FeMo{µ-σ,η-C(C6H4Me-4)CH2}(µ-CH2)(CO)5(η-C5H5)], [FeMo{µ-η3-C(C6H4Me-4)C(OMe)C(H)}(CO)5(η-C5H5)], and [FeMo{µ-η-SC(C6H4Me-4)}(CO)5(η-C5H5)]
Abstract
The compound [FeMo(µ-CC6H4Me-4)(CO)6(η-C5H5)] is a verstile reagent for studying the reactivity of an alkylidyne ligend bridging a heteronuclear metal-metal bond, as shown by its reactions with diazomethane, oxygen, and sulphur.
