  catalysts. These compounds have been found to be conveniently accessible from benzoic acids via Rh-catalyzed electrooxidative C–H/C–H couplings, giving valuable dihydrogen as the byproduct. In an undivided cell with Pt electrodes, RhCl3·3H2O catalyzes the oxidative carboxylate-directed ortho-homocoupling of various aromatic acids with a current efficiency of 67%. The protocol is operationally simple, tolerates

  The present invention relates to a highly bio-based polycarbonate ester and a method for producing same. The highly bio-based polycarbonate ester has a bio-based carbon content of 80% or more since the highly bio-based polycarbonate ester is obtained by copolymerization of 1,4:3,6-dianhydrohexitol, which is a bio-based monomer derived from biomass, and 1,4-cyclohexanedicarboxylate and/or terephthalate, and therefore, the highly bio-based polycarbonate ester is not only human-friendly and environmentally friendly, but also advantageous in terms of biodegradability.
