Abstract

The reactivity of the unusual oxyaryl dianionic ligand,(C6H2 t Bu2-3, 5-O-4) 2–, in the Bi3+ NCN pincer complex Ar′ Bi (C6H2 t Bu2-3, 5-O-4), 1,[Ar′= 2, 6-(Me2NCH2) 2C6H3] has been explored with small molecule substrates and electrophiles. The first insertion reactions of CO2 and COS into Bi–C bonds are observed with this oxyaryl dianionic ligand complex. These reactions generate new dianions that have quinoidal character similar to the ...
