Transition metal η2-vinyl complexes

A methyldiazene (HNNCH 3 )-derived species bound to the nitrogenase active-site FeMo cofactor: Implications for mechanism

“…The ENDOR spectroscopic studies reveal that the product alkene most likely is bound side-on to a single Fe atom of FeMo cofactor. Such side-on binding of alkenes (and alkynes) to metals is consistent with binding modes observed in metal complexes outside of proteins (16). An analogous study has characterized an intermediate trapped during proton reduction (17).…”

The synthesis and characterisation of some nickel(0) complexes with π-bounded vinylsilicon ligands; the molecular structure of [Ni{P(C6H5)3}2{η2-CH2CHSi(CH3)3}]

“…(2) New nickel(0) complexes (2,4,5,7) were fully, spectroscopically characterised. The other complexes (1,3,6) were synthesised by a simple, more efficient method than described in the literature. 1) is the first example of nickel complex with monovinylsilane whose crystal structure has been determined.…”

“…Transition metal-alkene p-complexes have attracted much attention because of their significance in organometallic synthesis and catalysis [1][2][3][4]. A lot of examples of complexes with p-bounded ligands are known but those containing vinyl derivatives of organosilicon compounds are still rare.…”

The Versatile Chemistry of Disilenides: Disila Analogues of Vinyl Anions as Synthons in Low-valent Silicon Chemistry

“…In view of the importance of carbon-based vinyl ligands in transition-metal chemistry and the different coordination modes that are realized there, 73 the disilenide transition metal chemistry, which so far was only hinted at, does offer exciting possibilities remaining to be explored.…”
