متن کاملReactions of Chromyl Chloride with Monocarboxylic Acids
Chromyl chloride was prepared by the literature method 3. A solution of formic acid in carbon tetra chloride was added dropwise to chromyl chloride diluted in the same solvent so that the reaction product was always in excess of formic acid. Since the reaction was violently exothermic, the reaction vessel was maintained at 0 °C throughout the addition. After a few minutes, the colour of the so...
متن کاملTransition Metal-Catalyzed Decarboxylative Coupling Reactions of Alkynyl Carboxylic Acids
The decarboxylative couplings of alkynyl carboxylic acids are an attractive area of research in organic chemistry, because the structure of aryl alkyne is one of the important building blocks for the synthesis of p-conjugated compounds. The use of alkynyl carboxylic acid as an alkyne source has several advantages in handling and storage. As a catalyst, palladium, copper, nickel, and silver were...
متن کاملMicrowave Irradiation Promoted Reactions of Orthoesters with Carboxylic Acid Hydrazides. Preparation of 1,3,4-Oxadiazoles
Rapid and highly efficient synthesis of 2- or 2,5-substituted 1,3,4-oxadiazoles by the condensation of aryl carboxylic acid hydrazides and orthoesters can be achieved under microwave irradiation using an unmodified commercial over in unsealed vessels.
متن کاملFe3O4@ZrO2-SO3H Nano-particles for esterification of carboxylic acids
In this work preparation of sulfonic acid functionalized magnetite encapsulated zirconia (Fe3O4@ZrO2-SO3H) has been reported. Structural, chemical, and magnetic properties of the magnetically supported catalyst have also been investigated by Fourier transform infrared (FT-IR) spectroscopy, wide angle X-ray diffraction spectroscopy (WXRD), thermal gravimetric analysis (TGA), energy dispersive X-...
