experimental part, p. 1130 - 1133 (2012/03/26)
An efficient, rapid, and green synthesis of functionalized pyrazoles has been accomplished under solvent-free conditions by the reaction of phenyl hydrazine, aldehydes and ethyl acetoacetate. This approach exploits the synthetic potential of microwave irr

experimental part, p. 2214 - 2222 (2011/10/18)
A variety of fully substituted pyrazoles were easily prepared through a three-component condensation of aldehydes, arylhydrazines, and ethyl acetoacetate in the presence of catalytic amounts of zinc triflate [Zn(OTf) under solvent-free conditions. Selecti

The nitrilimine 7, generated in situ from N-phenyl-C-(2-thienyl)formohydrazidoyl chloride 5 in chloroform in the presence of triethylamine, reacts with acrylonitrile, acrylamide and arylidene acetophenones to give exclusively the 5-substituted 2-pyrazolin
