In situ generation of radical initiators using amine-borane complexes for carbohalogenation of alkenes.

Atom transfer radical addition of alkyl halides to alkenes was developed using a low amount of a stable initiator, amine borane complexes. Thanks to a slow hydroboration step, the overall carbohalogenation process leads to good isolated yields.

Amine-borane complex-initiated SF5Cl radical addition on alkenes and alkynes.

The SF5Cl radical addition on unsaturated compounds was performed using an air-stable amine-borane complex as the radical initiator. This method showed to be complementary to the classic Et3B-mediated SF5Cl addition on alkenes and alkynes. A total of seven alkene and three alkyne derivatives were tested in the reaction, with yields ranging from 3% to 85%.
