  Ruthenium-Catalyzed Regioselectiveα-Alkylation of Ketones: The First Alkyl-Group Transfer from Trialkylamines to theα-C Atom of Ketones

  摘要：

  A new reaction: A ruthenium-catalyzed transfer of an alkyl group from a trialkylamine to the α-carbon atom of a ketone leads in good yields to α-alkylated ketones [Eq. (1)]. The reaction is applicable to a wide range of alkyl(alkyl), alkyl(aryl), and cyclic ketones, and in the case of unsymmetrical ketones it takes place regioselectively at the less hindered α-position.

  A versatile heterogeneous catalyst consisting of sub‐nanosized iridium clusters deposited on titania (Ir/TiO2‐NCs) promotes the direct tandem synthesis of quinoline derivatives from readily available nitroarenes and aliphatic alcohols under mild and additive‐free conditions (see scheme). The process tolerates the presence of various reactive functional groups and is highly selective.

  Nitroarenes are reductively cyclized with an array of tetraalkylammonium halides and trialkylarnmonium chlorides in the presence of a catalytic amount of a ruthenium catalyst along with tin(II) chloride dihydrate at 180° to afford the corresponding quinolines in moderate to good yields. The addition of tin(II) chloride dihydrate is necessary for the effective formation of quinolines and toluene is

  在催化量的钌催化剂和二水合氯化锡（II）的存在下，将四烷基卤化铵和三烷基氯化铵与硝基芳烃进行还原性环合，在180°下产生适量至良好收率的相应喹啉。为了有效形成喹啉，必须添加二水合氯化锡（II），甲苯是选择的溶剂。针对该催化过程，提出了一种反应途径，该反应途径包括首先将硝基芳烃还原为苯胺，然后将烷基铵卤化物转化为烷基胺，将烷基从烷基胺转移至苯胺以形成亚胺，使亚胺二聚，并进行杂环化。

  Anilines react with allylammonium chlorides in an aqueous medium (H2O–dioxane) in the presence of a catalytic amount of RuCl2(PPh3)3 together with SnCl2·2H2O to give the corresponding quinolines in moderate to good yields. The existence of SnCl2·2H2O is necessary for the effective formation of quinolines, and a reaction pathway involving amine exchange reaction between anilines and allylammonium chlorides
