The development of new or more sustainable, active, efficient, controlled, and selective
polymerization reactions or processes continues to be crucial for the synthesis of important …

1.1 Background Interest in ring-opening polymerization (ROP) reactions has gained
tremendous momentum in the course of the past two decades.(1) While the polymerization …

Ten years have passed since the conception of what was termed Lewis pair polymerization
(LPP) that employs Lewis acid and base in pairs to not only activate monomers but also …

We describe the synthesis of the new Zn–N‐heterocyclic carbene (NHC) alkoxide
complexes [(S, CNHC) ZnCl (OBn)] 2 (5) and [(O, CNHC) ZnCl (OBn)] 2 (6) for use as ring …

Reduction of CO2 emission is an important issue all over the world, and the development of
effective transformation methods of CO2 into valuable chemicals is highly desirable. Among …

Discrete two‐coordinate ZnII organocations of the type (NHC) Zn− R+ are reported, thanks to
NHC stabilization. In preliminary reactivity studies, such entities, which are direct cationic …

The present contribution reviews the synthesis, reactivity, and use in catalysis of NHC–Zn
complexes reported since 2013. NHC-stabilized Zn (II) species typically display enhanced …

A range of tetrahedral bis (formazanate) zinc complexes with different steric and electronic
properties of the formazanate ligands were synthesized. The solid-state structures for …

A backbone-substituted N-heterocyclic carbene (NHC) zinc complex, in combination with
alcohol initiators, has been shown to be an effective catalyst for the ring-opening …

The mechanism for ring-opening polymerization (ROP) of lactide catalyzed by Zn (C6F5) 2–
organic superbase Lewis pairs was investigated in the present work. Common organic …
