Abstract
Biorenewable dihydrolevoglucosenone (Cyrene™) is used as an effective dipolar aprotic solvent for Cu(0) wire-mediated RDRP of various monomers without external deoxygenation being applied. The solvent is used to give products with a broad range of molar masses (Mn∼ 700-28 000),in situchain extension and as low as 7.8 × 10−4eq. of [Cu(ii)Br2] relative to initiator.
