Rhodium-catalysed arylative annulation of 1,4-enynes with arylboronic acids†
Abstract
The rhodium(I)-catalysed arylative annulation of 1,4-enynes with arylboronic acids was investigated. The reaction was found to proceed via an addition–1,4-rhodium migration–addition sequence, affording the corresponding 1,1-disubstituted 3-(arylmethylene)indanes.
