Internal catalysis in covalent adaptable networks: phthalate monoester transesterification as a versatile dynamic crosslinking chemistry.

Journal of the American Chemical Society, 2019
Covalent adaptable networks (CANs) often make use of a highly active external catalysts to provide swift exchange of the dynamic chemical bonds. Alternatively, milder species can act as an internal catalyst when covalently attached to the matrix and in ...

Transesterification by Peptidyl Transferase

Nature, 1970
Peptidyl transferase, the enzyme which catalyses formation of peptide bonds, can be stimulated by CCA, the 3′-terminus of tRNA, to catalyse also a transesterification reaction involving nucleophilic attack of Met-tRNAfMet by ethanol to yield fMet-ethyl ester.

Transesterification reactions in molten polymers

Polymer Engineering & Science, 1987
Abstract The transesterification reaction of molten ethylene and vinyl alcohol copolymers (EVA), in presence of paraffinic alcohols and basic catalysts, leads to high conversion of the ester groups to secondary alcohol in both discontinuous and continuous processing equipment. Various kinds of alcohols and two different catalysts were

Base-Catalyzed Transesterification of Thionoesters

The Journal of Organic Chemistry, 2018
Here we report a convenient synthesis of thionoesters by base-catalyzed transesterification. Benzyl and alkyl thionobenzoates and thionoheterobenzoates were efficiently prepared using various alcohols catalyzed by the corresponding sodium alkoxide. This methodology features a broad substrate scope, good to excellent yields, short reaction times, while ...
