The 2-imidazolines were smoothly oxidized to the corresponding imidazoles in good yields using (diacetoxyiodo)benzene at room temperature.
2-Imidazolines were easily prepared in good yields from the reaction of aldehydes and ethylenediamine with iodine in the presence of potassium carbonate.
A catalytic oxidative cleavage of 1,3-diketones enables the synthesis of the corresponding carboxylic acids by aerobic photooxidation with iodine under irradiation with a high-pressure mercury lamp.
-mediated oxidative cross-coupling/cyclization of 2-(pyridin-2-yl)acetate derivatives and simple olefins provides a straightforward and efficient access to 1,3-di- and 1,2,3-trisubstituted indolizines in good yields. This operationally simple, functional-group-tolerant tandem approach provides an easy access to the broad range of biologically important benzamides. An efficient, metal-free domino protocol for the synthesis of benzamides from ethylarenes proceeds through the formation of triiodomethyl ketone intermediate in the presence of iodine as the promoter and TBHP as an oxidant followed by nucleophilic substitution with aqueous ammonia. An I/CHP-mediated cross-coupling reaction of isocyanides with readily accessible amines gives carbodiimides in good yields. An iodine-catalyzed oxidative C-H/N-H cross-coupling enables an efficient construction of α-ketoimides in good to excellent yields from methyl ketones and benzamidines hydrochloride under metal-free and peroxide-free conditions.
