Oxidative NHC-Catalysis as Organocatalytic Platform for the Synthesis of Polyester Oligomers by Step-Growth Polymerization

The application of N-heterocyclic carbene (NHC) catalysis to the polycondensation of diols and dialdehydes under oxidative conditions is herein presented for the synthesis of polyesters using fossil-based (ethylene glycol, phthalaldehydes) and bio-based (

Preparation method of dicarboxylic isosorbide

The invention provides a preparation method of a dicarboxylic isosorbide. According to the preparation method, sorbitol is taken as a raw material, 0.5 to 48h of dehydration is carried out in the presence of a dehydration catalyst at N2 atmosphere at 100 to 180 DEG C, a monoprotic acid and an esterification catalyst are added, reaction temperature is increased to 185 to 250 DEG C for 0.5 to 48h of esterification, and reduced pressure distillation is carried out so as to obtain the dicarboxylic isosorbide product. The dicarboxylic isosorbide is a novel biomass-based plasticizer, can be used for replacing phthalic acid ester in production of polyvinyl chloride products such as agricultural plastic mulching film. Product yield of the preparation method is high; production separation is convenient; the preparation method is friendly to the environment; and application prospect is promising.

Selective Esterification of 1,4:3,6-Dianhydro-D-glucitol

Esterification of 1,4:3,6-dianhydro-D-glucitol (1) with carboxylic acids in the presence of 4-dimethylaminopyridine and dicyclohexylcarbodiimide affords 2-exo-acylates 3 with high regioselectivity, in addition to small amounts of the isomeric 5-endo-acylates 4 and 2,5-diacylates 5.
