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”.
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 sonication effect are discussed. (C) 2004 Elsevier Ltd. All rights reserved.
