Nickel or Palladium-Catalyzed Decarbonylative Transformation of Carboxylic Acid Derivatives.

Chemistry - An Asian Journal, 2020
Carboxylic acid derivatives containing acyl halides, anhydrides, esters, amides and acyl nitriles are highly appealing electrophiles in transition-metal-catalyzed carbon-carbon bond-forming reactions due to their ready availability and low cost, which ...

Behavior of carboxylic acids and carboxylic anhydrides in sulfuric acid

Canadian Journal of Chemistry, 1967
The behavior of some carboxylic acids and anhydrides in sulfuric acid has been investigated by cryoscopic and conductimetric measurements in 100% H2SO4, cryoscopic measurements in aqueous H2SO4, and conductimetric titrations in dilute oleum.The previously established behavior of acetic anhydride in dehydrating sulfuric acid, [Formula: see text]is ...

Cobalt Pincer Complexes for Catalytic Reduction of Carboxylic Acid Esters.

Chemistry, 2018
A selection of cobalt(I) and cobalt(II) pincer type complexes with different substitution patterns was tested in the catalytic reduction of carboxylic acid esters to alcohols. The cobalt pincer type complex 4 is suitable for the hydrogenation of aromatic
