    Partial Deoxygenation of Glycerol Catalyzed by Iridium Pincer Complexes
    摘要:
    Iridium pincer complexes (POCOP)Ir(CO) (POCOP = kappa(3)-C6H3-1,3-[OP(Bu-t)(2)](2)) and substituted POCOP derivatives catalyze deoxygenation of glycerol to n-propanol and 1,3-propanediol in good yield under moderate conditions (acidic aqueous dioxane, 200 degrees C, 80 bar H-2). Catalyst solubility in the polar reaction mixture is improved by incorporation of a polar moiety in the para position of the POCOP phenyl ring, with the best results obtained with a dimethylamino substituent.

    Dehydrogenation of alcohols by three iridium pincer complexes, IrH(Cl)[2,6-(tBu2PO)2C6H3] (1), IrH(acetone)[2,6-(tBu2PO)2C6H3]}BF4} (2), and IrH(Cl)[2,5-(tBu2PCH2)2C5H2}Ru(C5H5)] (3), is reported, in both the presence and the absence of a sacrificial hydrogen acceptor.

    dehydrogenation has two high-barrier steps, namely the reaction of IrH2 with alcohol to give (POCOP)IrH(OR) (IrH(OR)) and subsequent β-elimination in the latter. Depending on the alcohol and reaction conditions, IrH(OR) can be formed via an associative pathway that includes proton transfer to the hydride or a dissociative mechanism that involves hydrogen elimination from IrH2 to give a 14e (POCOP)Ir species. Rapid
    (POCOP)Ir (POCOP = 2,6-( t Bu 2 PO) 2 C 6 H 3 )类型的钳形配合物是用于仲醇脱氢的高效催化剂。令我们惊讶的是,我们发现 (POCOP)IrH 2 ( IrH 2 ) 显示的转换频率在催化剂的更稀溶液中更高,这引发了对IrH 2醇脱氢的机理研究. 在这里,我们提供了强有力的证据,证明稀释加速与氢的限速传质有关,到目前为止,这在文献中还没有受到太多关注。使用实验和计算方法,我们表明脱氢有两个高阻隔步骤,即IrH 2与醇反应生成 (POCOP)IrH(OR) ( IrH(OR) ) 和随后的 β-消除。根据醇和反应条件,IrH(OR)可以通过包括质子转移到氢化物的缔合途径或涉及从IrH 2消除氢以产生 14e (POCOP)Ir 物质的解离机制形成。IrH(OR)的快速再氢化或溶解氢产生的 14e (POCOP)Ir 是导致催化剂在更浓溶液中的速率延
