Conversion des Cis- et Trans-Pyrazolines en Pyrazoles Sur Support Mineral Impregne de Nitrate Ferrique ou Cuivrique

Pyrazoles are prepared from cis- and trans-pyrazolines with good yield in dichloromethane under mild reaction conditions using the inexpensive clay-supported iron (III) nitrate "Clayfen" or copper (II) nitrate "Claycop".

Ultrasound-accelerated aromatisation of trans- and cis-pyrazolines under heterogeneous conditions using claycop

A simple, efficient and eco-friendly procedure has been developed for the aromatisation of various pyrazolines in heterogeneous media using clay-supported copper(II) nitrate (claycop) under ultrasound activation. The reaction rate enhancement and the soni

Synthesis of 1-Phenyl-3-aryl-benzofuranopyrazoles

Iodination of o-aroyloxyacetophenones (Ia-f) with iodine monochloride in acetic acid affords ω-iodo-2-aroyloxy-acetophenones (IIa-f) which on base catalysed Baker-Venkataraman transformation afford 2-aroylcoumaran-3-ones (IIIa-f).Compounds (IIIa-f) on ref
