The use of coordinating moieties as directing groups for the functionalisation aromatic carbon-hydrogen (C-H) bonds has become an efficient strategy selective construction new carbon-carbon (C-C) and carbon-heteroatom (C-X) in arenes. However many cannot be easily removed/modified from products after C-H functionalisation, thus limiting structural diversity products. This limitation can overcome by employing removable/modifiable or traceless which attached to starting materials detached In this tutorial review, we give overview recent advances emerging field have dramatically increased synthetic applicability processes.

While preparative electrolysis of organic molecules has been an active area research over the past century, modern synthetic chemists have generally reluctant to adopt this technology. In fact, electrochemical methods possess many benefits traditional reagent-based transformations, such as high functional group tolerance, mild conditions, and innate scalability sustainability. Outlook we highlight illustrative examples reactions in context synthesis complex molecules, showcasing intrinsic versus approaches. Our hope is that field will soon see widespread adoption community.

Towards "Oxidative-Ullmann-Goldberg" and "Oxidative-Buchwald-Hartwig" type amination reactions. This review focuses on the newly developed oxidative C-N bond formation techniques, applicable in field of organic synthesis. Particular emphasis is given to those which are classified as cross-dehydrogenative-couplings, through dual C-H N-H activation, thus formally extruding "H2" a by-product.

Abstract Synthetically useful functional groups, including ketones, amides, carbamates, carboxylic acids, aldehydes or ethers, have been identified as weakly coordinating directing groups in efficient ruthenium(II)‐catalyzed CH functionalizations. This strategy set the stage for versatile bond olefinations, oxygenations, nitrogenations and oxidative alkyne annulations among others. Thereby, step‐economical access to diversely decorated arenes heteroarenes was provided a sustainable fashion. magnified image

The functionalization of C–H bonds has created new approaches to preparing organic molecules by enabling strategic "disconnections" during the planning a synthetic route. Such functionalizations also have ability derivatize complex modifying one or more many bonds. For these reasons, researchers are developing types reactions and applications processes. These bond can be divided into two general classes: those directed coordination an existing functional group prior cleavage (directed) occurring without (undirected). undirected much less common challenging develop than reactions. This outlook will focus on functionalization, as well related that occur noncovalent association catalyst cleavage. inherent challenges conducting methods for being developed presented, along with factors govern selectivity in Finally, this discusses future directions research emphasis limitations must overcome if type methodology is become widely used academia industry.

Left- or right-handed C–H bond activation Although organic compounds consist mostly of carbon and hydrogen atoms, strategies for chemical synthesis have traditionally targeted the handful more reactive interspersed oxygens, nitrogens, halogens.
