  Synthesis of neutral nickel–methyl complexes with monodentate imines and their sequential insertion of carbon monoxide and imine

  摘要：

  Neutral nickel-imine complexes of the form (N boolean AND O)Ni(R)((RN)-N-1=C(H)R-2) (N boolean AND O = salicylaldiminato; R = CH3, Ph; R-1 = alkyl; R-2 = aryl) can be prepared by the reaction of (tmeda)Ni(CH3)(2), imine and the corresponding salicylaldiminato ligand. The addition of carbon monoxide to these complexes lead to the in situ generation of the corresponding nickel-acyl complexes. With N-methyl or N-benzyl substituted imines, these complexes reductively eliminate the phenolic and acyl ligands to generate esters. However, the less sterically encumbered 3,4-dihydroisoquinoline can couple with the nickel-acyl ligand to form 1,2-diamides in high yield. In situ H-1 NMR analysis suggests this reaction occurs via insertion of imine into the nickel-acyl bond to form a nickel-bound amide complex.[GRAPHICS](C) 2010 Elsevier B. V. All rights reserved.

• [Co(MeTAA)] Metalloradical Catalytic Route to Ketenes via Carbonylation of Carbene Radicals
  作者：Andrei Chirila、Kaj M. Vliet、Nanda D. Paul、Bas Bruin

  Activation of these carbene precursors by the metalloradical cobalt(II) catalyst affords CoIII‐carbene radicals, which subsequently react with carbon monoxide to form ketenes. In the presence of a nucleophile (imine, alcohol, or amine) in the reaction medium the ketene is immediately trapped, resulting in the desired products in a one‐pot synthetic protocol.
