photocatalytic protocol has been developed for the conversion of γ-mono- and γ,γ-disubstituted allyl carbonates in the presence of Umemoto's reagent to afford substituted six-membered cyclic carbonates. Variation and diversification of the carbonate ring substitution provides access to new monomers useful in ring-opening polymerization leading to polycarbonates with potentially tailored properties, as illustrated
