Journal ArticleDOI
Investigations in the catalytic species of the distannoxane-catalyzed transcarbamoylation
TL;DR: The 1,3-Dihalodistannoxanes show a high activity as catalysts in transcarbamoylation, explained by the weak coordinative properties of the halogens as mentioned in this paper.
Journal ArticleDOI
In situ generated “lanthanum(III) nitrate alkoxide” as a highly active and nearly neutral transesterification catalyst
TL;DR: In situ generated lanthanum(III) nitrate alkoxide is a highly active and nearly neutral transesterification catalyst, which can promote non-epimerized transesterization of α-substituted chiral carboxylic esters under reflux conditions.
Journal ArticleDOI
Multinuclear NMR Characterization of Co-cross-linking of Ethylene-co-vinylacetate and Ethylene-co-methylacrylate Polymer Blends in the Presence of Dibutyltin Oxide
TL;DR: The co-cross-linking reaction of co-vinylacetate (EVA) and EMA polymer blends in the presence of dibutyltin oxide in the molten state is an interchain redistrieval.
Journal ArticleDOI
Synthesis of Fluorinated Ketoheptoses as Specific Diagnostic Agents
TL;DR: The straightforward syntheses of six regioisomeric mono- and difluorinated D-manno-heptulose and Kamusol analogues represent promising probes for the detection and quantification of beta cells in vivo by 19F MRI techniques, which could help to investigate disease progression and potential candidates for the inhibition of tumour growth.

Mild Esterification and Transesterification of Carboxylic Acids Catalyzed by Tetracyanoethylene and Dicyanoketene Dimethyl Acetal
TL;DR: A π-acid tetracyanoethylene (TCNE) and its derivative dicyanoketene dimethyl acetal (DCKDMA) were found to catalyze esterification of lauric acid with various types of alcohols as mentioned in this paper.
