A Glycerol‐Based Deep Eutectic Solvent as Natural Medium and Organic Reductant for Homocoupling of (Hetero)Aryl Chlorides: a Green Route to 2,2’‐Bipyridine and Biaryl Scaffolds
نویسندگان
چکیده
A glycerol-based Deep Eutectic Solvent (DES) enables the Pd-catalyzed activation of (hetero)arylchlorides and promotes formation 2,2’-bipiyridines biaryls through an Ullmann-type homocoupling in smooth experimental conditions (80 °C) with Ca(OH)2 as a green base Pd/C heterogeneous catalyst. Noteworthy, coupling does not need addition external reducing agents, like metals, since glycerol present DES acts safe organic reductant. The catalytic system (DES-Pd/C) showed to be easily recyclable has been applied sustainable synthesis Abametapir drug.
