Abstract

5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere. ... In this paper, we present another example of the Rh-catalyzed reaction of arylboronic acids: a reaction of arylboronic acids with alkynes under a CO atmosphere to yield 2(5H)-furanones (2-butenolides). ... Scheme 1 Rhodium(I)-catalyzed carbonylative addition of phenylboronic acid to diphenylacetylene.
