Herein, we present m-C–H olefination on derivatives of phenylaceticacids by tethering with a simple nitrile-based template through palladium catalysis. Notably, the versatility of the method is evaluated with a wide range of phenylaceticacid derivatives for obtaining the meta-olefination products in fair to excellent yields with outstanding selectivities under mild conditions. Significantly, the

Radical fluoroalkylation of alkenes has been developed by electrochemical reduction of fluoroalkyl sulfones. A series of electron-deficientalkenes readily undergo hydrofluoroalkylation in good to excellent yields. This chemistry represents the first example of electrochemical generation of fluoroalkyl radicals from sulfones, which are used for practical radical fluoroalkylation of organic compounds

Use for the treatment of diseases having an inflammatory basis of compounds or salts thereof, having the following general formula (I): A-X1-L-(W)p-NO2 wherein A contains the radical of a drug, X1 and W are bivalent radicals, L is a covalent bond or oxygen, sulphur, NR1c wherein R1c is H or a C1-C5 linear or branched alkyl.
Late-stage C(sp3)–H functionalization of unactivated azines: the traceless Tf switching process offers ample opportunities for site-selective derivatization of heteroaryls, allowing for the rapid increase of molecular complexity.
Development of a novel strategy for the palladium-catalyzed selective meta-C–H activation of α-substituted cinnamates and their heterocyclic analogues with various alkenes using nitrile as a directing group (DG) has been described. Importantly, we introduced naphthoquinone, benzoquinones, maleimides and sulfolene as coupling partners in the meta-C–H activation reaction for the first time. Notably,
