Rhodium-catalyzed addition/ring-opening reaction of arylboronic acids with cyclobutanones.
Cyclobutanones react with arylboronic acids in the presence of a catalytic amount of Rh(I) complex to afford butyrophenone derivatives through the addition of an arylrhodium(I) species to the carbonyl group, followed by ring-opening of the resulting rhodium(I) cyclobutanolate. [reaction: see text]
