Reactivity of metal complexes supported by ligands with functionalized pendant ar

Abstract

Multidentate phosphines connected by terphenyl linkers have been employ multimetallic complexes. The central arene of the terphenyl unit acts as a labile variety of modes as a function of metal and oxidn. state. Addnl., this arene can to redox and H-transfer chem. Mo complexes with P-arene-P pincers show reductive coupling of two CO mols. demonstrating the ability of such ligands to s activation chem. Variants with catechol and hydroquinone moieties perform transfer chem. Mechanistic studies of reactions with O_2 show that second-sphere O_2 activation steps. The coordination chem. of these systems and reactivit discussed.
