  • Title: Stereospecific Ni-catalyzed cross-coupling of potassium alkenyltrifluoroborates with alkyl halides.
    Author: Molander GA, Argintaru OA.
    Journal: Org Lett; 2014 Apr 04; 16(7):1904-7. PubMed ID: 24666316.
    Abstract:
    A general method for the alkenylation of alkyl electrophiles using nearly stoichiometric amounts of the air- and moisture-stable potassium organotrifluoroborates has been developed. Various functional groups were tolerated on both the nucleophilic and electrophilic partner. Reactions of highly substituted E- and Z-alkenyltrifluoroborates, as well as vinyl- and propenyltrifluoroborates, were successful, and no loss of stereochemistry or regiochemistry was observed.
