Efficient cobalt(III)-catalyzed (hetero)aryl and alkenyl C-H hydroarylations of maleimides and maleate esters have been achieved under remarkably mild reaction conditions. Thus, the versatile cobalt(III) catalyst [Cp CoI2(CO)] showed excellent atom-and step-economy as well as high chemo- and site-selectivity providing expedient access to pharmacologically useful succinimides with wide functional group tolerance.

Rhodium(III)-catalyzed C-H bond functionalization for the synthesis of beta-aryl aldehydes and ketones from (hetero)aryl oximes, pyri(mi)dine, as well as pyrazoles and alpha,beta-unsaturated carbonyl compounds has been developed under exceedingly mild reaction conditions. Thus, the versatile rhodium(III) catalysis features high step- and atom-economy, oxidant-free reaction conditions, and broad substrate scope.
