Abstract

The present review considers all the literature data on methods developed for the synthesis of phosphorus compounds containing pyrazole rings starting from their appearance up to the 2011. The described methods for the synthesis of phosphorus compounds containing pyrazole rings can be divided into three routes: a) direct phosphorylation of pyrazole rings, b) ring closure of acyclic phosphorus compounds with different reagents into phosphono-pyrazoles and c) cyclization of side functional groups to give isolated and fused phosphorus heterocyclic systems containing pyrazole rings.
