A catalytic amidation protocol mediated by 2,2,2-trifluoroethanol has been developed, facilitating the condensation of unactivated esters and amines, furnishing both secondary and tertiary amides. The complete scope and limitations of the method are described, along with modified conditions for challenging substrates such as acyclic secondary amines and chiral esters with retention of chiral in...

A low pressure microflow system was developed for palladium-catalyzed multiphase carbonylation reactions in an ionic liquid. The microflow system resulted in superior selectivity and higher yields in carbonylative Sonogashira coupling and amidation reactions of aryl iodides compared to the conventional batch system.

The complex [Tpm(*,Br)Cu(NCMe)]BF4 (Tpm(*,Br) = HC(3,5-Me2-4-Br-pyrazolyl)3) catalyses the aziridination of alkenes and the amidation of cyclic ethers with chloramine-T as the nitrene source and the ionic liquid [bmim]PF6 as the reaction medium (bmim = 1-n-butyl-3-methylimidazolium). High conversions have been obtained over several cycles of catalyst recovery and reuse.

Carbon nanotube conducting arrays were constructed via consecutive amidation reactions with the aid of a linker molecule and a condensation agent on a patterned amine-terminated glass substrate. The electrical resistivity of the nanotube films was sensitive to the degree of coverage for the substrate, making it possible to tailor nanotube multilayers suitable for use in micro- or nanoscale elec...

A Cu-catalyzed aromatic C-H amidation with phthalimide under oxygen as a terminal oxidant without using additional additives has been achieved. This reaction has the broad substrate scope and shows moderate to good yields in most cases. This method is complementary to the previously reported metal-catalyzed C-H amination systems.

The direct synthesis of amides by insertion into the C-H bond of aldehydes is shown to be a practical procedure through application of cheap, readily available catalysts generated in situ from copper(i) halides and pyridine.

Two experiments were performed to compare the effect of pectin and its hydrophobic derivatives on homeostasis of cholesterol and cecal metabolism in male young rats. Control rats were fed a diet supplemented with palm fat and cholesterol (50 and 10 g/kg, respectively). Rats of other groups were fed the same diet containing citrus pectin or octadecylpectinamide (60 g/kg). Diets were fed for 4 we...

The title compound, C(16)H(18)N(2)O(2)S, was obtained as an unexpected product while attempting to form carbon-nitro-gen bonds by catalytic amidation. The mol-ecule displays an E conformation about the C=N double bond. The planes of the two aromatic rings in the mol-ecule form a dihedral angle of 47.06 (9)°.

The solution-phase synthesis of high quality LaOBr nanocrystals has been realized by single source precursors under the assistance of an organic salt (TBAB) and characterized by XRD and TEM. The unique crystallization process of LaOBr NCs is demonstrated and dictated by the amidation reaction. The X-ray luminescence of (Tm, Tb, Eu)-doped LaOBr NCs has also been characterized.

A copper-mediated aerobic coupling reaction enables direct amidation of heterocycles or aromatics having weakly acidic C-H bonds with a variety of nitrogen nucleophiles. These reactions provide efficient access to many biologically important skeletons, including ones with the potential to serve as inhibitors of HMTs.
