An efficient cross-coupling of 3-iodochromones with triarylbismuths under catalytic palladium conditions is reported. Triarylbismuths were employed as substoichiometric multicoupling nucleophiles for the synthesis of a variety of substituted isoflavones. Under the established protocol, cross-coupling reactions were found to be very efficient, furnishing high yields of products.
