Synthesis and reactivity of the 17 e- complex [Re(II)Br4(CO)2]2 : A convenient entry into rhenium(II) chemistry

Zobi, Fabio ; Kromer, Lukas ; Spingler, Bernhard ; Alberto, Roger

In: Inorganic Chemistry, 2009, vol. 48, no. 18, p. 8965-8970

The reduction of (Et(4)N)[Re(III)Br(4)(CO)(2)] (1) by 0.5 equiv of tetrakis- dimethylaminoethylene in acetonitrile yields directly the air-stable, 17-electron Re(II) synthon (Et(4)N)(2)[Re(II)Br(4)(CO)(2)] (2) in nearly quantitative yield. The versatility of 2 as a synthon for Re(II) chemistry was demonstrated by substitution reactions of [Re(II)Br(4)(CO)(2)](2-) with different mono-, bi-,...

Transfer hydrogenation of ketones and activated olefins using chelating NHC ruthenium complexes

Horn, Sabine ; Gandolfi, Claudio ; Albrecht, Martin

In: European Journal of Inorganic Chemistry, 2011, vol. 2011, no. 18, p. 2863–2868

N-Heterocyclic carbene (NHC) ruthenium complexes consisting of different donor substituents attached to the NHC ligand efficiently catalyse the transfer hydrogenation of ketones and of activated olefins in α,β-unsaturated ketones to give saturated alcohols. The most active catalyst precursor contains a tethered olefin as a hemilabile donor site. This complex also converts nitriles and,...
