The effect of the degree of substitution on the solubility of cellulose acetoacetates in water: A molecular dynamics simulation and density functional theory study.

Carbohydrate Research, 2020
The effect of the degree of substitution (DS) on the aqueous solubility of cellulose acetoacetates (CAA) was investigated by molecular dynamics simulations and density functional theory calculations.

Photoreaction of Acetoacetate

Bulletin of the Chemical Society of Japan, 1970
Abstract Methyl acetoacetate was irradiated in the presence of cyclohexene to afford methyl 3-cyclohexyl-3-hydroxybutyrate (VIII), methyl 3-cyclohexenyl-3-hydroxybutyrate (IX), two oxetanes (Xa and Xb), and cyclohexene dimers. In contrast to acetylacetone, acetoacetate behaves as a saturated ketone rather than as an α,β-unsaturated ester

Copper-Catalyzed Synthesis of 5-Carboxyl-4-perfluoroalkyl Triazoles.

Organic Letters, 2021
A facile, scalable synthesis of previously inaccessible trifluoromethyl and perfluoroalkyl triazoles is disclosed. Mediated by copper, this catalytic protocol enables access to 4-perfluoroalkyl triazoles from commodity chemicals.

Synthesis of Ester-Substituted Indolizines from 2-Propargyloxypyridines and 1,3-Dicarbonyls.

Journal of Organic Chemistry, 2022
Two new complementary Au(I)-catalyzed methods for the preparation of ester-substituted indolizines from easily accessible 2-propargyloxypyridines and either acetoacetates or dimethyl malonate are reported.

A Colorimetric Method for Estimating Acetoacetate

American Journal of Clinical Pathology, 1965
The use of sodium nitroprussidc in a qualitative color reaction with acetoacetic acid has a history dating back to 1884, when Legal reported the development of a red color in the presence of acetoacetic acid and alkali. This color was intensified from red to purple by acidification with acetic acid soon after the alkali was added. In 1908, Rothera used
