Synthesis of pincer ligands and their respective metallated complexes
Pincer ligands continue to remain of increasing interest for their rigid meridional configuration to metal centers, which provide excellent thermal and chemical stability in organometallic systems. The predictable arrangement of such ligands allow them to be effective complexes in catalytic cycles. We explore the synthesis of new and versatile pincer ligands based on a bis-(2-phosphinopyrrol) motif with methylene, silyl and phosphino linkers. Their respective metal complexes have been prepared and heavily characterized.
