Advances in computational chemistry and catalysis: Honouring Jumras Limtrakul’s 72nd birthday
Abstract
A calcium catalyst was found to be highly active for ROP of lactide. DFT calculations revealed that hydrogen-bonding of N–H moieties with lactide and large metal size are responsible for high catalytic performance.

Abstract
One ligand, many possibilities! Altering the metal, the number of metal atoms as well as the second ligand strongly affects the catalytic activity of the related β-oxo-δ-diiminate complexes in the ring-opening polymerization of L-lactide.

Chemistry for a Sustainable World – Celebrating Our Community Tackling Global Challenges
Abstract
Since the seminal work by Trofimenko (1960s), scorpionate ligands have emerged as pivotal components in the field of coordination chemistry and catalysis. They have demonstrated a remarkable versatility for the preparation of sustainable polymers.

Abstract
New magnesium complexes were used as catalysts for the ring opening polymerization of cyclic esters to produce degradable polymers. In the ROP of macrolactones, good activity and control were achieved at room temperature, conditions generally prohibitive for macrolactones.
