Recent advances in transition metal-catalyzed Csp2-monofluoro-, difluoro-, perfluoromethylation and trifluoromethylthiolation
In the last few years, transition metal-mediated reactions have joined the toolbox of chemists working in the field of fluorination for Life-Science oriented research. The successful execution of transition metal-catalyzed carbon-fluorine bond formation has become a landmark achievement in fluorine chemistry. This rapidly growing research field has been the subject of some excellent reviews. Ou...
متن کاملRecent advances in C-S bond formation via C-H bond functionalization and decarboxylation.
The development of mild and general methods for C-S bond formation has received significant attention because the C-S bond is indispensable in many important biological and pharmaceutical compounds. Early examples for the synthesis of C-S bonds are generally limited to the condensation reaction between a metal thiolate and an organic halide. Recent chemical approaches for C-S bond formation, ba...
متن کاملRecent advances in C(sp3)–H bond functionalization via metal–carbene insertions
The recent development of intermolecular C-H insertion in the application of C(sp(3))-H bond functionalizations, especially for light alkanes, is reviewed. The challenging problem of regioselectivity in C-H bond insertions has been tackled by the use of sterically bulky metal catalysts, such as metal porphyrins and silver(I) complexes. In some cases, high regioselectivity and enantioselectivity...
متن کاملRecent Advances in Transition-Metal-Catalyzed, Directed Aryl C–H/N–H Cross-Coupling Reactions
Abstract Amination and amidation of aryl compounds using a transition-metal-catalyzed cross-coupling reaction typically involves prefunctionalization or preoxidation of either partner. In recent years, a new class of transition-metal-catalyzed cross-dehydrogenative coupling reaction has been developed for the direct formation of aryl C–N bonds. This short review highlights the substantial progr...
متن کاملRapid Room‐Temperature, Chemoselective Csp2 −Csp2 Coupling of Poly(pseudo)halogenated Arenes Enabled by Palladium(I) Catalysis in Air
While chemoselectivities in Pd0 -catalyzed coupling reactions are frequently non-intuitive and a result of a complex interplay of ligand/catalyst, substrate, and reaction conditions, we herein report a general method based on PdI that allows for an a priori predictable chemoselective Csp2 -Csp2 coupling at C-Br in preference to C-OTf and C-Cl bonds, regardless of the electronic or steric bias o...
