diversities of bench-stable and easy-to-use sulfonium salts and arenesulfonyl chlorides. Both developed methods, namely the light-mediated photoredox and electrophilic arylation, showed good efficiency, and are feasible for the preparation of 3-arylchromones in good-to-excellent yields. This work showcases the first described attempt where the sulfonium salts and arenesulfonyl chlorides were successfully utilized
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.
