A concise and atom-economical Suzuki-Miyaura coupling of trialkyl- and triarylboranes with aryl halides is a general and practical method that efficiently utilizes peralkyl and peraryl groups of the unactivated trialkyl- and triarylboranes. The trialkylboranes could be generated in situ from hydroboration of terminal alkenes.
