Selective, Catalytic Carbon−Carbon Bond Activation and Functionalization Promoted by Late Transition Metal Catalysts
摘要:
The selective catalytic activation and functionalization of carbon-carbon bonds in a series of substituted cyclopropane substrates has been developed using commercially available transition metal catalysts. Catalytic hydrogenation and olefination procedures, tolerant of a range of functional groups, have been discovered. Introduction of a chelate-assisting substituent such as [PPh2] is effective in altering the kinetic selectivity and lowering the activation barrier for the catalytic processes.

A regioselective radical fluoroalkylphosphorylation of unactivated alkenes is developed by a one-pot reaction of (bis)homoallylic alcohols, phosphine chlorides, and fluoroalkyl iodides under compact fluorescence light (CFL) irradiation. This protocol employs a novel radical rearrangement of alkoxyphosphine to achieve the unusual installing of a phosphoryl in the inner side of the terminal olefins by
