A photo-induced carboxylation reaction of allylic C-H bonds of simple alkenes with CO2 is prompted by means of a ketone and a copper complex. The unique carboxylation reaction proceeds through a sequence of an endergonic photoreaction of ketones with alkenes forming homoallyl alcohol intermediates and a thermal copper-catalyzed allyl transfer reaction from the homoallyl alcohols to CO2 through C-C bond cleavage. An allylic C-H bond of simple alkenes is carboxylated with CO2 in the presence of a substoichiometric amount of a ketone and a catalytic amount of a copper complex under UV irradiation (see scheme).
