Abstract Indirect electrocatalytic conversion of cheap organic raw materials via the activation S─H and N─H bonds into value‐added S─N/S─S chemicals for industrial rubber production is a promising strategy to realize atomic economic reaction, during which kinetic inhibition that associated with electron transfer at electrode/electrolyte interface in traditional direct electrocatalysis can be eliminated achieve higher performance. In this work, series di‐copper‐substituted...

A new sequential approach for 2-vinylanilines utilizing aryl carboxylic acids as stable, inexpensive and widely available arylating reagents is described. Employing a Pd-POVs catalyst system, this protocol not only overcoming the restriction barrier of decarboxylative coupling to ortho-substituted substrates, but also provides site-special create C(sp2)-N C(sp2)-C(sp2) bonds. Mechanistic experiments suggest cleavage C(sp2)-COOH gives priority C(sp2)-X bond in reaction.
