Abstract
The reaction of 1-arylpyrazoles with CO and ethylene in the presence of Ru3(CO)12 resulted in regioselective carbonylation at the ortho C-H bonds. While it is found that the pyrazole ring also functions as the directing group for C-H bond cleavage, the efficiency of the reaction depends on the position of the pyrazole ring.
