  An efficient heterogeneous catalytic system for chemoselective hydrogenation of unsaturated ketones in aqueous medium

  摘要：

  A highly chemoselective and green heterogeneous catalytic system of immobilized Ru(II)-phenanthroline complexes on amino functionalised MCM-41 material for the chemoselective hydrogenation of unsaturated ketones to unsaturated alcohols is demonstrated using water as a solvent The XRD and FTIR spectra show the highly ordered hexagonal nature of the MCM-41 even after encapsulation of the ruthenium complex The complex retains its configuration after anchoring as was confirmed by FTIR and UV-Vis analysis The detailed reaction parametric effect was studied for the hydrogenation of 3 methylpent-3-en-2-one to achieve complete conversion up to >99% chemoselectivity of 3-methylpent-3-en-2 ol The anchored heterogeneous catalysts were recycled effectively and reused five times with marginal changes in activity and selectivity The use of water as a solvent not only afforded high activity for the hydroge nation reaction compared to organic solvents but also afforded a green process Crown Copyright (C) 2010 Published by Elsevier Ltd All rights reserved

  Acyclic internal alkenes are a class of challenging substrates in asymmetric Heck-type reactions due to difficulties related to both reactivity and selectivity control. Employing acyclic alkenyl alcohols, an asymmetric Heck–Matsuda reaction is developed through the strategy of chiral anion phase transfer. Various chiral ketones could be obtained in high levels of enantioselectivity. A catalytic amount

  由于与反应性和选择性控制有关的困难，无环内烯烃是不对称Heck型反应中一类具有挑战性的底物。利用无环烯基醇，通过手性阴离子相转移策略发展了不对称的Heck-Matsuda反应。可以高水平的对映选择性获得各种手性酮。催化量的二甲基亚砜（DMSO）作为添加剂对于抑制氢化钯介导的副反应至关重要。

  Positional and stereochemical selectivity in the isomerization of terminal alkenes to internal alkenes is observed using the cis-Mo(CO)4(PPh3)2 precatalyst. A p-toluenesulfonic acid (TsOH) cocatalyst is essential for catalyst activity. Various functionalized terminal alkenes have been converted to the corresponding 2-alkenes, generally favoring the Z isomer with selectivity as high as 8:1 Z:E at high

  使用顺式-Mo（CO）4（PPh 3）2预催化剂观察到末端烯烃异构化为内部烯烃的位置和立体化学选择性。甲p -甲苯磺酸（TsOH）助催化剂为催化剂活性是必需的。各种官能化的末端烯烃已被转化为相应的2-烯烃，在高转化率下通常有利于Z异构体，其选择性高达8：1 Z：E。通过31 P NMR对催化剂引发机理的研究表明，顺式-Mo（CO）4（PPh 3）2在高温下与TsOH反应生成磷化氢键合的Mo氢化物（MoH）物种。催化可通过将末端烯烃的2，1-插入MoH基团和立体选择性β-氢化物消除以产生（Z）-2-烯烃来进行。

  An (IrCp)-Cp-III* complex (2) bearing a triazenide ligand functionalized with pyrazole was synthesized and fully characterized by spectroscopic methods and the structure confirmed by X-ray diffraction studies. The catalytic activity of 2 and the control complex 3, which lacks of pyrazole in its structure, was evaluated in the reduction of aryl-ketones, alkyl-ketones, alpha,beta-unsaturated and gamma, delta-unsaturated ketones. The catalytic system, using either 2 or 3, exhibited good to excellent selectivity when tested with ketones and alkenones at 90 degrees C in 2-propanol as hydrogen source under base-free conditions. Reactivity of 2 in 2-propanol and NaH gave a neutral metal hydride (4) while in the absence of base gave two major cationic hydrides species (5 and 6).

  A general and direct synthesis of dicarboxylic acids including industrially important adipic acid by palladium‐catalyzed dicarbonylation of allylic alcohol is reported. Specifically, the combination of PdCl2 and a bisphosphine ligand (HeMaRaphos) promotes two different carbonylation reactions with high activity and excellent selectivity.
