    摘要:
    The quinoline-based pincer nickel(II) complexes kappa(N),kappa(N),kappa(N) -{R2N-C6H4-(mu-N)-C9H6N}NiX (((NNNQ)-N-R2)NiCl: R = Me) 2a; R = Et, 2b) were synthesized by the reaction of the ligand precursors ((NNNQ)-N-R2)H (R = Me, 1a; R = Et, 1b) with (DME)NiCl2 in the presence of Et3N. Similarly, the pincer mickel(II) derivatives ((NNNQ)-N-R2)NiX (R = Me, X = Br, 3a; R = Et, X = Br, 3b; R = Me, X = OAc, 4a) were obtained by treatment of the ligands ((NNNQ)-N-R2)H with the nickel precursor (THF)(2)NiBr2 or Ni(QAc)(2). All of these complexes were characterized by H-1 and C-13 NMR spectroscopy as well as by elemental analysis. Further, the molecular structures of 2a and 3a,b were elucidated by X-ray crystallography. Complex 2a is found to be an efficient catalyst for the direct C-H bond alkylation of substituted benzothiazoles and oxazoles with various unactivated alkyl halides containing beta-hydrogens under mild reaction conditions. The catalyst 2a is very robust and was recycled and reused five times for the alkylation reaction without a decrease in its catalytic activity. Preliminary studies reveal that the catalyst 2a acts as an active catalyst and the alkylation reaction appears to operate via a radical pathway.
