Synthesis and Anionic Ring-Opening Polymerization of a Novel Aromatic Cyclic Carbonate Having Binapthyl Structure

A novel aromatic cyclic carbonate (3) having binaphthyl structure was prepared by reaction of 2,2'-binapthol with 4-nitrophenyl chloroformate in the presence of a tert-amine. 3 polymerized very efficiently with potassium tert-butoxide at 20 deg C to give coresponding linear polycarbonate with Mn 12800 (Mw/Mn 1.34) in 94percent yield.
