[InCl4]-catalyzed addition of hydrazones to β-diketones: An efficient regioselective synthesis of pyrazoles and pyrazole-fused cyclohexanones

The Lewis acidic room-temperature ionic liquid, [bmim][InCl4], was found to be an efficient catalyst for the regio-selective synthesis of fully substituted pyrazoles and pyrazole-fused cyclohexanones through condensation of hydrazones with symm

1,3-Dipolar Cycloaddition of Four Hydrazonoyl Chlorides to β-Diketones and α,β-Unsaturated Ketones

The 1,3-dipolar cycloaddition of four hydrazonoyl chloride derivatives with the sodium salt of unsymmetrical β-diketones (benzoylacetone) offers a versatile method for the regioselective synthesis of 2H-pyrazoles in a similar fashion to the cycloaddition of the nitrilimides with α,β-unsaturated ketones and esters. The structures of the prepared isomeric pyrazole and pyrazoline derivatives were established by spectroscopic and chemical methods.
