Dual-catalytic decarbonylation of fatty acid methyl esters to form olefins

The homogeneous dehydrative decarbonylation of fatty acid methyl esters (FAMEs) to form olefins is reported. In order to facilitate cleavage of the unactivated acyl C-O bond of the alkyl ester, a one pot dual-catalytic directing group strategy was developed through optimization of the individual transesterification and decarbonylation reaction steps.

Selective esterification of aliphatic carboxylic acids in the presence of aromatic carboxylic acids over monoammonium salt of 12-tungstophosphoric acid

Monoammonium salt of 12-tungstophosphoric acid [(NH4)H 2PW12O40] was found to be a practical and useful heterogeneous catalyst for an efficient and selective esterification of aliphatic carboxylic acids with alcohols in the presence of aromatic carboxylic acids. The heteropoly acid-based heterogeneous catalyst has the advantages of a simple workup procedure, water insolubility, and good activity. Copyright Taylor & Francis LLC.

Esterification of carboxylic acids with alcohols under microwave irradiation in the presence of zinc triflatet

The esterification of aliphatic and aromatic carboxylic acids with various alcohols (1°, 2°, 3°, benzylic) was studied under microwave irradiation in the presence of zinc triflate as catalyst; the reaction times were short and the yield of reactions was good to excellent.

Esters, retroesters, and a retroamide of palmitic acid: Pool for the first selective inhibitors of N-palmitoylethanolamine-selective acid amidase

Cyclohexyl hexadecanoate, hexadecyl propionate, and N-(3-hydroxypropionyl)pentadecanamide, respectively ester, retroester, and retroamide derivatives of N-palmitoylethanolamine, represent the first selective inhibitors of "N-palmitoylethanolamine hydrolase" described so far. These compounds are devoid of affinity for CB1 and CB 2 receptors and characterized by high percentages of inhibition of N-palmitoylethanolamine-selective acid amidase (84.0, 70.5, and 76.7% inhibition at 100 μM, respectively) with much lower inhibitory effect on either fatty acid amide hydrolase or the uptake of anandamide.

Process for the preparation of carboxylic benzyl esters

Carboxylic benzyl esters can be prepared by reacting benzyl chloride with carboxylic acids in the presence of one or more quaternary ammonium carboxylates as catalyst.

Fatty acid esters of aromatic alcohols and their use in cosmetic formulations

The present invention relates to compounds according to the structure: Wherein R1is a C11to C21saturated or unsaturated, linear or branched hydrocarbon or a saturated or unsaturated hydrocarbon containing a pendant hydroxyl group, preferably on a carbon atom in a position alpha or beta to the keto group of the ester moiety; X is CH2, OCH2CH2or HC═CHCH2; and R2is H, OCH3, CH3or CH2CH3. These compounds exhibit use in personal care products as dry emollients as well as providing additional characteristics including solvency, dispersants, gloss-enhancing agents, solubilizing agents and melting-point depressants, lubricants, viscosity modulating agents and skin protection factor boosters.

Convenient synthesis of benzyl and allyl esters using benzyl and allyl 2,2,2-trichloro-acetimidate

Benzyl and allyl 2,2,2-trichloroacetimidate are efficient reagents for the preparation of benzyl and allyl esters of carboxylic acids in the presence of a catalytic amount of boron trifluoride-diethyl ether complex.

METAL-CATALYZED SYNTHESIS OF CARBOXYLIC ESTERS UTILIZING (E)-PHENYL 2-PYRIDYL KETONE O-ACYLOXIMES (PPAO)

(E)-Phenyl 2-pyridyl ketone O-acyloximes (PPAO) could be highly activated by metal ions such as Fe(3+), Cu(2+), and Zn(2+), and the most effective catalyst for the synthesis of carboxylic esters was found to be Zn(2+).Furthermore, sterically hindered carboxylic esters were easily obtained utilizing PPAOs and alcoholates in high yields.
