Photocatalytic C−H activation and C−C coupling of monohydric alcohols
Catalysis Communications, 2021 Monohydric alcohols, such as methanol, ethanol, are useful chemical building blocks that can be facilely produced from various carbon resources. The direct conversion of alcohols into high-value-added chemicals, in particular diols, is attractive but ...

Murahashi Cross‐Coupling at −78 °C: A One‐Pot Procedure for Sequential C−C/C−C, C−C/C−N, and C−C/C−S Cross‐Coupling of Bromo‐Chloro‐Arenes [PDF]
Chemistry – A European Journal, 2019 AbstractThe coupling of organolithium reagents, including strongly hindered examples, at cryogenic temperatures (as low as −78 °C) has been achieved with high‐reactivity Pd‐NHC catalysts. A temperature‐dependent chemoselectivity trigger has been developed for the selective coupling of aryl bromides in the presence of chlorides.

Oxidative electrochemical aryl C–C coupling of spiropyrans [PDF]
Chemical Communications, 2013 The isolation and definitive assignment of the species formed upon electrochemical oxidation of nitro-spiropyran (SP) is reported. The oxidative aryl C-C coupling at the indoline moiety of the radical cation to form covalent dimers of the ring-closed form is demonstrated. The coupling is blocked with a methyl substituent para to the indoline nitrogen.
