New Paradigms for Organic Catalysts: The First Organocatalytic Living Polymerization.

Fredrik Nederberg1, Eric F Connor1, Michael Möller1, Thierry Glauser1, James L Hedrick1.   

Abstract

A metal-free approach to the living ring-opening polymerization (ROP, shown schematically) of lactide has been developed using strongly basic amines such as 4-(dimethylamino)pyridine as transesterification catalysts. These organic catalysts must be used in combination with a nucleophile such as an alcohol, which is the actual initiating species.
