A sustainable route to converting carbon–hydrogen into carbon–carbon bonds
Hydrogen atom transfer is a fundamental reaction that is oxidative in most cases. The direct conversion of C–H to C–C bonds through photocatalysed hydrogen atom transfer is mainly limited to redox neutral reactions. The few non-redox neutral reactions reported are oxidative and require aggressive oxidants or fragile dual-catalytic systems to remove the extra electrons. Funded by the Marie Skłodowska-Curie Actions programme, the HAT-TRICK project plans to combine photocatalysed hydrogen atom transfer, electrochemistry and flow chemistry to deliver a simple and game-changing technology to drive these net-oxidation reactions sustainably. HAT-TRICK will open new avenues in organic synthesis, enabling cross-dehydrogenative couplings, alkene functionalisation and alkane dehydrogenation.
