Carbonylation with Acid Catalysts Koch Reaction The synthesis of carboxylic acids from olefins, carbon monoxide and water catalyzed by carbonyls was discussed in detail in the previous chapter. The same components also react in the presence of acid catalysts to give carboxylic acids. ... RNJ Falbe...
The pyrrolidinecarboxylic functionalized ionic liquid, 1-butyl-3-methylimidazolium-(S)-2-pyrrolidinecarboxylic acid salt ([bmim][Pro]), was prepared using an improved procedure. α,β-Unsaturated carbonyl compounds were selectively synthesized and high yields (88%–97%) were obtained at room temperat...
Reaction Pathways and Energy Barriers for Alkaline Hydrolysis of Carboxylic Acid Esters in Water Studied by a Hybrid Supermolecule-Polarizable Continuum Ap... Reaction pathways, solvent effects, and energy barriers have been determined for the base-catalyzed hydrolysis of two representative alkyl esters ...

A [RuH(CO)(py–NP)(PPh3)2]Cl (1) catalyst is found to be effective for catalytic transformation of primary alcohols, including amino alcohols, to the corresponding carboxylic acid salts and two molecules of hydrogen with alkaline water. The reaction proceeds via acceptorless dehydrogenation of al...
The heteromeric HOF HcOF-101 was obtained by cocrystallization of 1 and the o-alkoxycarboxylic acid derivative 13 [53]. The resultant HOF was subjected to a thiol-ene crosslinking reaction in the presence of ethanedithiol, which formed covalently linked stable porous materials. Tetracarboxylic acids...
