CWE/15/2017 Current World Environment 0973-4929 2320-8031 Enviro Research Publishers CWE--73-00 环境可接受的合成2 -[(5 / -(潜艇tituted phenyl)-1/ -phenyl) pyrazolyl] pyrroles 1 , Department of Chemistry, RTM Nagpur University, Nagpur, 440 033, India. 2006-07-15 10.12944/CWE.1.1.08 Volume 1 Volume 1 45-50 Abstract

An efficient synthesis of 2-[(5/-(substituted phenyl)-1/ -phenyl) pyrazolyl] pyrroles III (a-m) starting from 2-acetyl pyrrole I and 2-[substituted benz-1/(propene-1//-one)] Pyrroles II (a-m), in the presence of phenyl hydrazine, 2-[(5/-(4//-substituted phenyl)-1/ -phenyl) pyrazolyl] pyrroles III (a-m) has been synthesized in microwave oven for the first time. On comparing with the classical methods, this method has advantages such as shorter reaction time, better yield, simple workup and environmental acceptability.

Keywords Pyrrole Pyrazole Phenyl Hydrazine
