Dedicated to Professor Shinji Murai for his great contribution to the chemistry of catalytic C–H bond activation.
Abstract
An iridium-catalyzed acylmethylation and a rhodium-catalyzed amidation of naphthalene derivatives are reported, adopting sulfoxonium ylides and dioxazolones as carbene and nitrene transfer agents, respectively. The use of SMe group as a directing group was key to ensure the peri-selective functionalization, and it can be easily removed or diversely transformed to other synthetically useful functionalities after the catalysis.
Key words
