title: Mild synthesis of chalcones via rhodium(III)-catalyzed C-C coupling of arenes and cyclopropenones.
abstract: A Rh(III)-catalyzed aryl C-H bond insertion into cyclopropenones via a C-H activation pathway has been reported. A series of arenes bearing directing groups such as 2-pyridyl, 2-pyrimidyl, N-pyrazyl, and oxime can be applicable, providing chalcones in excellent yields under mild conditions. Several possible Rh(III) intermediates in this reaction were investigated.
