A general intermolecular
reductive Heck reaction of organohalides
with both terminal and internal unactivated aliphatic alkenes has
been first realized in high yield with complete anti-Markovnikov selectivity.
The challenging vinyl bromides, aryl chlorides, and polysubstituted
internal alkenes were first applied. More than 100 remote carbofunctionalized
alkyl carboxylic acid derivatives were rapidly synthesized from easily
accessible starting materials. The synthesis of drug molecules has
further demonstrated the wide synthetic utility of this scalable strategy.
Preliminary mechanistic studies are consistent with the proposed catalytic
cycle.
