An alkenylation of alkyl electrophiles using nearly stoichiometric amounts of air- and moisture-stable potassium organotrifluoroborates tolerates various functional groups on both the nucleophilic and electrophilic partner. Reactions of highly substituted E- and Z-alkenyltrifluoroborates, as well as vinyl- and propenyltrifluoroborates, were successful with retention of stereochemistry and regiochemistry.
