(Chemical Equation Presented) Suitable conditions were found for the Suzuki-Miyaura cross-coupling reaction of potassium cyclopropyl-and cyclobutyltrifluoroborates with aryl chlorides. Both of these secondary alkyl trifluoroborates coupled in moderate to excellent yield with electron-rich, electron-poor, and hindered aryl chlorides to give a variety of substituted aryl cyclopropanes and cyclobutanes.
