(Chemical Equation Presented) A reactive rhodium(0) metalloradical capable of binuclear activation of an aromatic C-H bond of PPh3 is disclosed. Kinetic measurements and density functional theory calculations reveal a binuclear mechanism: two metalloradicals add to a 'double bond' of the aromatic substrate while approaching the rate limiting C-H activation step (TS). Such aromatic C-H bond activation with Rh0 metalloradicals potentially produces kinetically labile RhI-aryl and RhI-H species, and thus, this could become a viable new approach to hydrocarbon functionalization.

Chemical Equation Presented Radical changes: One single P-Rh-P angle determines whether the odd electron in the paramagnetic complex [Rh(trop2PPh)(PPh3)] is delocalized over the whole molecule (see picture, blue) or is localized on the P - Rh unit (red). The two energetically almost degenerate electromers exist in a fast equilibrium, and the red complex has the highest spin density at Rh of all low valent Rh complexes observed to date.
