RT journal article T1 Microwave-Enhanced Coupling of Carboxylic Acids with Liquid Ketones and Cyclic Ethers Using Tetrabutylammonium Iodide/t-Butyl Hydroperoxide A1 Macías Benítez, Pablo A1 Moreno Dorado, Francisco Javier A1 Guerra Martínez, Francisco Miguel A2 Química Orgánica K1 carboxylic acid K1 ketone K1 cyclic ether K1 oxidative coupling K1 microwave irradiation K1 ester preparation AB The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butyl hydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional heating.
