A Ni-catalyzed Suzuki-Miyaura coupling of primary and secondary alkyl halides including alkyl chlorides with alkenyl-(9-BBN) reagents allows - also in combination with one pot hydroboration of terminal alkynes - the expedited synthesis of functionalized alkyl alkenes from readily available alkynes with complete (E)-selectivity.
