Photocatalytic multicomponent alkene dicarbofunctionalization via PCET/nickel dual catalysis

) bond formation under visible light and redox-neutral conditions. The method proceeds directly from secondary and tertiary alcohols, exhibits broad functional-group tolerance. Notably, employing a chiral Ni catalyst enables the first enantioselective variant of this type of PCET mediated transformation. This work establishes a general platform for deconstructive alkene difunctionalization from simple alcohol feedstocks, expanding the synthetic reach of PCET in dual catalytic radical chemistry.
