A novel catalyst consisting of a Schiff base-copper complex on surface-modified silica-coated ferrite nanoparticles was been prepared and used for oxidative C-O cross-coupling reactions of 1,3-dicarbonyl compounds with formamides for the synthesis of enol

Treatment of benzylamines with esters at an elevated temperature are expected to give amides. However, in the presence of TBAI/TBHP, esters possessing a methylene carbon α-to oxygen with benzylamines provide bis-esters rather than the expected amides. Benzylamines under oxidative conditions generate less nucleophilic carboxylates, which couples at the sp3 C-H bonds of esters and cyclic ethers to give bis-acyl ketals and α-acyloxy ethers, respectively.

A practical and efficient construction of C-O bonds via oxidative cross-coupling reaction of aldehydes and ethers has been realized under open air. When 2 mol% copper was used as the catalyst, various α-acyloxy ethers were obtained with up to 93% isolated

A copper-catalyzed cross-dehydrogenative coupling strategy has been developed for the synthesis of two classes of esters from simple solvents. The reaction of methylarenes with cyclic ethers resulted in α-acyloxy ethers involving four sp3 C-H cleavages, while treatment of methylarenes with cycloalkanes led to the formation of allyl esters at the expense of six consecutive sp3 C-H bonds.

The copper-catalyzed formation of C-O bonds by oxidative coupling of benzylic alcohols with ethers was realized in open air. A series of α-acyloxy ethers were obtained in good yields with aqueous tert-butyl hydroperoxide as the oxidant. The copper-catalyzed formation of C-O bonds by oxidative coupling of benzylic alcohols with ethers is realized in open air. A series of α-acyloxy ethers were obtained in good yields with aqueous tert-butyl hydroperoxide as the oxidant.

An efficient metal free oxidative esterification of sp3 C-H bonds (adjacent to an oxygen atom) in simple solvents like 1,4-dioxane, tetrahydropyran, tetrahydrofuran and ethyl acetate has been achieved using terminal aryl alkenes and alkynes as
Direct catalytic anti-markovnikov addition of carboxylic acids to alkenes
Perkowski, Andrew J.,Nicewicz, David A.
supporting information, p. 10334 - 10337 (2013/08/23)
A direct catalytic anti-Markovnikov addition of carboxylic acids to alkenes is reported. The catalyst system is comprised of the Fukuzumi acridinium photooxidant (1) and a substoichiometric quantity of a hydrogen-atom donor. Oxidizable olefins, such as styrenes, trisubstituted aliphatic alkenes, and enamides, can be employed along with a variety of carboxylic acids to afford the anti-Markovnikov addition adducts exclusively. A deuterium-labeling experiment lends insight to the potential mechanism.

The creme de la creme! A practical and simple Bu 4NI-catalyzed C-O bond formation was achieved by using a cross-dehydrogenative coupling (CDC) reaction with tert-butyl hydroperoxide (TBHP) as the ultimate oxidant (see scheme; R1=aryl
Effect of hydroxyl group substituents on pyran ring on hydrolysis rate of benzoates: 2-Tetrahydropyranyl benzoate
Hussain,Truelove
, p. 235 - 236 (2007/10/08)
The hydrolysis 0f 2-tetrahydropyranyl benzoate was followed spectrophotometrically at 240 nm and was first order with respect to the compound, independent of pH, and very sensitive to solvent polarity and had an isotope effect (kD2O?kH2O) near unity. The pH-independent hydrolysis rate about 1 x 106 times faster than that of the corresponding glucosyl benzoate. The results suggest that the presence of hydroxyl groups on the pyran ring has tremendous effect on the hydrolysis rate of these compounds.
