Oxidative coupling of carbonyl compounds by using pentavalent biphenyl-2,2'-ylenebismuth reagents
p-Tolylbiphenyl-2,2 '-ylenebismuth bis(trifluoromethanesulfonate) reacted with lithium enolates derived from ketones, carboxylic esters, and thioesters to afford the corresponding oxidative coupling products in good to high yields.
