(3-Butyl-1-methylimidazole)(1,5-cyclooctadiene)rhodium chloride [Rh(Ibm)(cod)Cl] was found to be an efficient catalyst in the carbonylative arylation of allenols with arylboronicacids in the presence of carbonmonoxide. Efficient, simple, and versatile methods for the synthesis of 2-methylene-1-arylbut-3-en-1-ones have thus been developed.
