摘要

Abstract The first application of inexpensive commercially available sulfinate salts to produce β-keto sulfones directly from alkynes via aerobic oxysulfonylation has been developed. It is a highly selective (undesired Glaser–Hay homo-coupling and ATRA process totally suppressed) general method of functionalization of alkynes on water at room temperature involving FeCl 3/K 2 S 2 O 8 catalyzed formation of sulfonyl radicals from ...
