Parallel microscale experimentation was used to develop general conditions for the Suzuki-Miyaura cross-coupling of diversely functionalized primary alkyltrifluoroborates with a variety of aryl chlorides. The conditions that were previously identified to promote the cross-coupling of secondary alkyltrifluoroborates with aryl chlorides were not optimal for primary alkyltrifluoroborates.
