- Rhodium-Catalyzed Electrooxidative C?H Olefination of Benzamides
-
Metal-catalyzed chelation-assisted C?H olefinations have emerged as powerful tools for the construction of functionalized alkenes. Herein, we describe the rhoda-electrocatalyzed C?H activation/alkenylation of arenes. The olefinations of challenging electron-poor benzamides were thus accomplished in a fully dehydrogenative fashion under electrochemical conditions, avoiding stoichiometric chemical oxidants, and with H2 as the only byproduct. This versatile alkenylation reaction also features broad substrate scope and used electricity as a green oxidant.

- Rh(III)-catalyzed Directed C-H Olefination using an oxidizing directing group: Mild, efficient, and versatile
-
An efficient Rh(III)-catalyzed oxidative olefination by directed C-H bond activation of N-methoxybenzamides is reported. In this mild, practical, selective, and high-yielding process, the N-O bond acts as an internal oxidant. In addition, simply changing the substituent of the directing/oxidizing group results in the selective formation of valuable tetrahydroisoquinolinone products.

-
A good neighborhood! The metal-catalyzed oxidative C-H functionalization of electron-rich arenes is well-established, but analogous reactions of electron-poor substrates are rare. A new application makes use of common electron-withdrawing functional groups (COMe, CONH2, CONEt 2) in the rhodium-catalyzed oxidative Heck reaction to generate complex organic molecules. Cp= I·5-C5Me 5.
