Treatment of divalent ytterbium hydride complex [(TpAd,iPr)Yb(H)(THF)] (TpAd,iPr = hydrotris(3-adamantyl-5-isopropyl- pyrazolyl)borate) (1) with CO, CO2 and CS2 resulted in the formation of divalent ytterbium ethenediolate complex [(TpAd,iPr)Yb]2(cis-OCH=CHO) (2), formate complex...
The mechanism of dinitrogen cleavage by a PNP-coordinated dititanium polyhydride complex has been computationally investigated. A “multi-state reactivity” scenario has been disclosed for the whole process of N2 coordination and...
Copper(I) complexes of a new participative triphosphane ligand (<b>2<sup>H</sup></b>) have been prepared and structurally characterized, in particular [Cu(<b>2<sup>H</sup></b>)I] and [Cu(<b>2</b>)]<sub>2</sub>. Hydrogenation of the latter species afforded the trimetallic hydride species [Cu<sub>3</sub>(<b>2</b>)<sub>2</sub>(µ-H)] or in the presence of BEt<sub>3</sub>, [Cu(<b>2<sup>H</sup></b>)(HBEt<sub>3</sub>)]. Their formation evidences transient formation of [Cu(<b>2<sup>H</sup></b>)H] formed by hydrogenolysis of the Cu‒<br>N bond of [Cu(<b>2</b>)]<sub>2</sub>. [Cu(<b>2<sup>H</sup></b>)(HBEt<sub>3</sub>)] behaves like a hydride complex and inserts CO<sub>2</sub> to yield the formate product [Cu(<b>2<sup>H</sup></b>)(O<sub>2</sub>CH)].<br>

Herein, by applying zirconium-hydride complex as the catalyst, the transfer hydrogenation of quinoline and indole derivatives with ammonia borane as the proton and hydride source is achieved. Up to 94%...
Intrigued by the successful oxidative addition of a P-H bond to univalent Ga[Al(ORF)4] giving the unprecedented dicationic gallium hydride complex [H-Ga(PPh3)3][Al(ORF)4]2 (ORF = OC(CF3)3), the oxidative addition of E-Cl containing...
