    Pincer-Ligated Nickel Hydridoborate Complexes: the Dormant Species in Catalytic Reduction of Carbon Dioxide with Boranes
    摘要:
    Nickel pincer complexes of the type [2,6-(R2PO)(2)C6H3]NiH (R = Bu-t, 1a; R = Pr-i, 1b; R = (c)Pe, 1c) react with BH3 center dot THF to produce borohydride complexes [2,6-(R2PO)(2)C6H3]Ni(eta(2)-BH4) (2a-c), as confirmed by NMR and IR spectroscopy, X-ray crystallography, and elemental analysis. The reactions are irreversible at room temperature but reversible at 60 degrees C. Compound 1a exchanges its hydrogen on the nickel with the borane hydrogen of 9-BBN or HBcat, but does not form any observable adduct. The less bulky hydride complexes 1b and 1c, however, yield nickel dihydridoborate complexes reversibly at room temperature when mixed with 9-BBN and HBcat. The dihydridoborate ligand in these complexes adopts an eta(2)-coordination mode, as suggested by ER. spectroscopy and X-ray crystallography. Under the catalytic influence of 1a-c, reduction of CO2 leads to the methoxide level when 9-BBN or HBcat is employed as the reducing agent. The best catalyst, 1a, involves bulky substituents on the phosphorus donor atoms. Catalytic reactions involving 1b and 1c are less efficient because of the formation of dihydridoborate complexes as the dormant species as well as partial decomposition of the catalysts by the boranes.

The catalytic system is long‐lived and remarkably efficient with high turnover numbers (TONs) and turnover frequencies (TOFs) achieved. The mild reaction conditions allow a wide variety of aldehydes, including base‐sensitive ones, to catalytically react with acetonitrile.

    A one-pot procedure has been developed for the direct and atom-economical preparation of the pincer-type complexes (R′-POCOPR)NiCl (R′-POCOPR = κP,κC,κP-(2,6-(R2PO)2-R′n-C6H3−n); R = i-Pr, Ph; R′n = H, 4-OMe, 4-COOMe, 3,5-(t-Bu)2). This convenient synthetic protocol involves heating a 1 : 2 : 1–2 mixture of resorcinol (or its substituted derivatives), R2PCl, and nickel powder in toluene (at 100 °C) or acetonitrile (at 75 °C) for 18 h. The target nickel compounds can be obtained from this procedure in up to 93% yield. Using metallic palladium in this protocol instead of nickel gives the corresponding palladium complexes in low yields only (ca. 10%).

    and ligand exchange reactions between the nickel isothiocyanate and nickel azide complexes have been investigated. The metathesis reactions with thiocyanate/azide complexes are faster with a less electron rich and more sterically accessible nickel center. The thermodynamic stability of these nickel complexes has been rationalized using hard-soft acid-base theory (HSAB theory); a harder ligand prefers

    alkynyl complexes [2,6-(R2PO)2C6H3]NiCCPh (7a–b) and H2 are not produced in the nickel system. The more bulky hydride complex [2,6-(tBu2PO)2C6H3]NiH (4c) shows no reactivity towards phenylacetylene. Catalytic hydrogenation of phenylacetylene with 4a–b takes place at an elevated temperature (70–100 °C) and proves to be heterogeneous. The structures of 5b, 6a, 7a and 7b have been studied by X-ray crystallography
