摘要：

(Chemical Equation Presented) Ever-increasing circles: Seven-membered-ring ketones are constructed by a rhodium(I)-catalyzed arylative ring-expansion reaction of alkyne-substituted aryl cyclobutanones, in which two C-C bond-forming and one C-C bond-cleaving events occur consecutively (see scheme). © 2005 Wiley-VCH Verlag GmbH & Co.
