    (E)-Enynyldialkylboranes, thus obtained, gave regio- and/or stereospecifically defined corresponding conjugated alkynones by alkaline hydrogen peroxide oxidation, conjugated (E)-enynes by protonolysis with acetic acid, and conjugated enynes bearing an unsaturated group on the internal alkenyl carbon atom by bis(acetylacetonato)copper-catalyzed cross-coupling reaction with allyl bromide or 1-bromo-1-hexyne respectively

    acidato ligands (BHetA) including carboxylato (O,O), thioacetato (O,S), amidato (O,N), thioamidato (N,S), and amidinato (N,N), have been prepared by reaction of the dinuclear precursor [Rh(μ‐Cl)(IPr)(η2‐coe)]2 with the corresponding anionic BHetA species. The RhI‐NHC‐BHetA compounds catalyze the dimerization of aryl alkynes, showing excellent selectivity for the head‐to‐tail enynes. Among them, the acetanilidato‐based

    日期:2017.1
    Copper (I) or copper (II) salts and oxides promote regioselective head-to-head additive dimerization of aromatic and aliphatic terminal alkynes in the presence a catalytic amount of diethylphosphite. The reaction proceeds under ambient conditions without any added base with the formation of 1,4-disubstituted 1,3-enynes with the E isomer as major product in good to excellent yields. A plausible mechanism

    作者:Christopher J. Pell、Oleg V. Ozerov
    DOI:10.1021/cs5009317
    日期:2014.10.3
    A series of pincer complexes of Rh has been prepared and tested as catalysts for the dimerization of terminal alkynes. The pincers included aryl/bis(phosphinite) POCOP, aryl/bis(phosphine) PCP, and diarylamido/bis(phosphine) PNP ligands. RhI complexes of the general form (pincer)Rh(SiPr2) or (pincer)Rh(H2) were used as catalysts. In addition, the apparent donating ability of the pincer ligands was
    已经制备了一系列Rh的钳形配合物,并已作为末端炔的二聚化催化剂进行了测试。钳子包括芳基/双(次膦酸酯)POCOP,芳基/双(膦)PCP和二芳基酰胺/双(膦)PNP配体。一般形式为(钳子)Rh(S i Pr 2)或(钳子)Rh(H 2)的Rh I配合物用作催化剂。此外,通过IR光谱通过(钳)Rh(CO)络合物中的羰基拉伸频率来测量钳配体的表观供体能力。所有调查的Rh配合物均充当4-乙炔基甲苯,1-己炔或三甲基甲硅烷基乙炔二聚化的催化剂。产品是E和宝石的混合物-烯炔异构体,在某些情况下带有少量低聚物。所述ž除了在两个反应中未观察到-enyne异构体。对于E-或宝石-烯炔产物,没有一种催化剂显示出有用的选择性。但是,带有P i Pr 2供体臂的POCOP基催化剂比以前报道的Pinch Rh催化剂表现得更快,寿命更长(最高20000吨)。
