Photocatalytic Synthesis of Substituted Cyclic Carbonate Monomers for Ring‐Opening Polymerization

An operationally mild, ruthenium‐based 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...
