  • Synthesis and first X-ray structures of cobalt(II) and cobalt(III) complexes bearing 2,4-dioxo-alkanoic acid dialkylamide ligands
    作者:Jian Wang、Nicholas A Morra、Hongda Zhao、Jeffrey ST Gorman、Vincent Lynch、Robert McDonald、John F Reichwein、Brian L Pagenkopf
    DOI:10.1139/v08-151
    日期:2009.1.1
    report we describe the first crystal structures of 2,4-dioxo-alkanoic acid dialkylamide complexes for both Co(II) and Co(III) salts. The Co(II) structures show an unprecedented arrangement of atoms, with a central Co(II)(H2O)6 flanked by two Co(II) atoms each coordinated with three anionic chelating ligands. The dimeric Co(III) structures show two anionic chelating ligands and bridging hydroxyl groups.Key

  • Gram-Scale Synthesis of the Co(nmp)2 Catalyst to Prepare trans-2,5-Disubstituted Tetrahydrofurans by the Aerobic Oxidative Cyclization of Pent-4-en-1-ols

    日期:2020.3
    Co(nmp)2 is an efficient catalyst for the aerobic oxidative cyclization of pent-4-en-1-ols to give 5-hydroxymethyl trans-tetrahydrofurans (THFs) as single diastereomers in high yield. The trans-THF pharmacophore is of interest because it is found in many biologically active natural products. The three-step synthesis of Co(nmp)2 described here gives the catalyst as a fine powder in 80–85% overall yield

    A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.

    have been synthesized and demonstrated as active for the C(sp(3))-H borylation of a range of substituted alkyl arenes using B2Pin2 (Pin = pinacolate) as the boron source. At longer reaction times, rare examples of polyborylation were observed, and in the case of toluene, all three benzylic C-H positions were functionalized. Coupling benzylic C-H activation with alkyl isomerization enabled a base-metal-catalyzed
    已经合成了带有 α-二亚胺配体的二烷基钴和双(羧酸盐)配合物,并证明对使用 B2Pin2(Pin = pinacolate)作为硼源的一系列取代烷基芳烃的 C(sp(3))-H 硼酸化具有活性. 在更长的反应时间内,观察到了罕见的多硼化例子,在甲苯的情况下,所有三个苄基 CH 位置都被官能化。将苄基 CH 活化与烷基异构化相结合,可以使用贱金属催化方法对远程未活化的 C(sp(3))-H 键进行硼酸化。

    The synthesis of the cobalt hydrides of formula CoH(CO)4—n[P(n-C4H9)3]n (n=2, 3) are described and their chemical and spectroscopic properties are discussed. The complexes homogeneously catalyze the hydrogenation of alkynes and aldehydes and isomerization of olefins. These reactions are discussed in relation to the aldehyde hydrogenation catalyzed under hydroformylation conditions by the Co2(CO)8 system
