A mild, practical protocol for the decarboxylative alkylation of heteroarenes has been accomplished via iron photocatalysis. diverse range carboxylic acids readily undergo oxidative decarboxylation and then couple with a broad array in this transformation. The photoexcited state lifetimes complexes are typically much shorter than those iridium ruthenium complexes. Here we describe our effort on photocatalysis by utilizing intramolecular charge transfer pathway iron-carboxylate
A mild and efficient protocol for the intramolecular aromatic C-H oxygenation of 2-biphenylcarboxylic acids has been achieved via iron photocatalysis. The with a diverse array substituents at both phenyl rings could furnish products in good to excellent yields. We speculate that aryl carboxylate-iron(III) complexes should generate aroyloxy radicals iron(II) upon visible light irradiation.
Abstract An efficient and operationally simple Ni‐catalyzed amination protocol has been developed. This methodology features a Ni II salt, an organic base catalytic amounts of both pyridinium additive Zn metal. A diverse number (hetero)aryl halides were coupled successfully with primary secondary alkyl amines, anilines in good to excellent yields. Similarly, benzophenone imine gave the corresponding N ‐arylation product yield.
