Abstract:
The growing interest in pincer ligand synthesis and their transition metal chemistry is due to their remarkable thermal stability to tolerate harsh reaction conditions during catalysis. In last one decade several pincer ligands have been synthesized and their metal chemistry and catalytic applications have been explored. This article summarizes briefly the synthesis and metal complexes of a few rare and unusual pincer ligands, viz, cyclodiphosphazane appended PCP, tri- and tetrametaphosphacyclophanes, triazole based PCP, PCS and PCN systems, SiPSi and PCyP pincer ligands.
