N,N‐Dimethylhydrazine as a Reversible Derivatization Agent to Promote the Hydroxymethylation of Furfural with Formaldehyde

open access: yesChemSusChem, EarlyView.
The reversible derivation of the –CHO group of furfural with N,N‐Dimethylhydrazine not only restores the nucleophilicity of the furan ring toward formaldehyde but also opens an alternative mechanism to the classical acid‐catalyzed pathway for the selective hydroxymethylation of the furanic ring of furfural.

Highly Isoselective Polymerization of rac‐Lactide by Zinc Complexes of Sequential Tetradentate {ONNN} Ligands

open access: yesChemSusChem, EarlyView.
Zinc complexes of a new family of sequential {ONNN} ligands are introduced and employed for the ring‐opening polymerization of rac‐lactide. The pyridine‐amine‐imine‐phenolate complexes lead to a rare combination of very high activities and isoselectivities yielding stereomultiblock poly(lactic acid) while their isomers are less active and essentially ...

From Spirocyclic Germanium Alkoxides to their Fluorido Germanates

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Spirocyclic germanium salicyl alcoholates potentially meet the requirement as molecular precursors for twin polymerization, which is defined as a concerted formation of two polymeric materials from a so‐called twin monomer. Two examples of such germanium alkoxides and their associated fluorido germanates are reported and aspects of their chirality and ...

Acyclic Diene Metathesis Polymerization Approach for Synthesis of Biobased Polyesters: Summary of Recent Reports

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The synthesis of biobased polyesters, including soluble polymer networks, displaying better tensile properties beyond polyolefins by adopting ADMET polymerization, and the post‐modification for preparation of the multiblock copolymers and the composite have been reviewed.

The Fusion of Elemental Sulfur With Waste Cooking Oil‐Based Derivatives: Beyond Renewability

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The fuse of two waste streams, elemental sulfur and waste cooking oil, is enabled by Inverse Vulcanization. The process might ensure the closed‐loop production of polymeric materials for a wide range of applications, beyond its sole potential renewability.
