Recent Findings in Cyclometallation of Meta-Substituted Aryl Ligands by Platinum Group Metal Complexes by Caryl-R Bond Activation (R=H, CR3,SiR3)

Abstract

Cyclometallation of aryl ligands with two donor substituents in the meta positions occurs through Caryl-R bond activation. This procedure, which is outlined below (Y=N-, P- and S-donor ligands; R=H, CR3, SiR3), has been used for the preparation of organometallic complexes such as 1 (P=PPh2) with interesting catalytic and electronic properties.
