Hydrogen-bonding organocatalysts for ring-opening polymerization
Coralie Thomas,Brigitte Bibal +1 more
TL;DR: In this paper, the design of catalysts, strategies of activation and mechanistic elucidations are highlighted in the ring-opening polymerization of cyclic esters and carbonates, hydrogen-bonding organocatalysis offers an interesting alternative to metal-based and enzymatic catalysis to access biocompatible and biodegradable polymers.

Ring-Opening Polymerization of l-Lactide Catalyzed by an Organocatalytic System Combining Acidic and Basic Sites
Joji Kadota,Dražen Pavlović,Jean-Pierre Desvergne,Brigitte Bibal,Frédéric Peruch,Alain Deffieux +5 more
TL;DR: In this article, organocatalytic systems containing both basic and acidic sites, which can activate simultaneously the chain end and the monomer, were investigated in the ring-opening polymerization of L-lactide.

(Thio)Amidoindoles and (Thio)Amidobenzimidazoles: An Investigation of Their Hydrogen‐Bonding and Organocatalytic Properties in the Ring‐Opening Polymerization of Lactide
Sylvain Koeller,Joji Kadota,Frédéric Peruch,Alain Deffieux,Noël Pinaud,Isabelle Pianet,Stéphane Massip,Jean-Michel Léger,Jean-Pierre Desvergne,Brigitte Bibal +9 more
TL;DR: The mechanism of the ring-opening polymerization (ROP) of lactide catalyzed by two partner hydrogen-bonding organocatalysts was explored and it was shown that simultaneous weak hydrogen bonds do exist to activate the reagents.

Ring-Opening Polymerization of l-Lactide Efficiently Triggered by an Amido-Indole. X-ray Structure of a Complex between l-Lactide and the Hydrogen-Bonding Organocatalyst
Sylvain Koeller,Joji Kadota,Alain Deffieux,Frédéric Peruch,Stéphane Massip,Jean-Michel Léger,Jean-Pierre Desvergne,Brigitte Bibal +7 more
TL;DR: The first X-ray structure of the complex between a H-bonding organocatalyst and l-lactide also revealed a tight H- bonded network between the dimer (1e)(2) and L- lactide.

Ring-opening polymerization of lactones using supramolecular organocatalysts under simple conditions
TL;DR: In this article, a metal-free system composed of two H-bonding components, a phenol derivative to activate the monomer, and DBU, which enhanced the nucleophilicity of the initiator and the propagating chain, was used for ring-opening polymerizations of δ-valerolactone (δ-VL) and e-caprolactone(e-CL).
