  1,3-diols with arylhydrazines via acceptorless dehydrogenative coupling reactions to selectively synthesize pyrazoles and 2-pyrazolines were reported, which were based on Ru3(CO)12/NHC-phosphine-phosphine catalytic systems. The reactions featured low catalyst loading, high selectivity, wide substrate scope, and good yields, with only water and hydrogen gas (H2) as the byproducts.

  本文报道了基于Ru 3 (CO) 12 /NHC-膦-膦催化体系的1,3-二醇与芳基肼通过无受体脱氢偶联反应选择性合成吡唑和2-吡唑啉的不同转化。该反应具有催化剂负载量低、选择性高、底物范围广、收率高的特点，仅副产物水和氢气（H 2 ）。
