Herein, the divergent transformations of 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.
Organic Letters published new progress about Hydrazines Role: RCT (Reactant), RACT (Reactant or Reagent). 13788-92-6 belongs to class pyrazoles-derivatives, and the molecular formula is C9H7BrN2, Synthetic Route of 13788-92-6.
