| Summary: | A series of novel NNN pincer manganese complexes based on pyrazole skeleton <b>4</b> were efficiently synthesized in a two-step process. All of the new complexes were fully characterized by <sup>1</sup>H, <sup>13</sup>C NMR spectra. Furthermore, the molecular structures of complexes <b>4a</b> and <b>4c</b> were also determined by X-ray single-crystal diffraction. The manganese(I) catalysts obtained showed efficient catalytic activity in the α-alkylation reaction of ketones with alcohols. Under optimal reaction conditions, the expected products were procured with moderate to high yields. |
