The first example of carbonylation of triarylbismuthines: remarkable rhodium(I) catalysis
Abstract
Triarylbismuthines (Ar3Bi: Ar = C6H5, 4-MeC6H4, 4-MeOC6H4, 4-ClC6H4) react with atmospheric pressure of carbon monoxide in acetonitrile, tetrahydrofuran or methanol at 25 °C in the presence of a catalytic amount of either [RhCl(CO)2]2 or RhCl3·3H2O to produce the corresponding diaryl ketones in good yields, methyl benzoates being also formed in methanol.
