Evidence for a Precursor Complex in CH Hydrogen Atom Transfer Reactions Mediated by a Manganese (IV) Oxo Complex

Aquest mateix article està publicat a l’edició alemanya d’’Angewandte Chemie’ (ISSN 0044-8249, EISSN 1521-3757), 2011, vol.123, núm. 25, p. 5766-5771. DOI http://dx.doi.org/10.1002/ange.201100907

HAT trick: [MnIV(OH)2(H,MePytacn)]2+ (A) and [MnIV(O)(OH)(H,MePytacn)]+ (B) differ in their reactions with CH bonds: compound A engages in typical single-step hydrogen atom transfer (HAT) reactions, whereas B first forms a substrate–B encounter complex (C; see scheme). This equilibrium alters the relative CH reactivity from that expected from CH bond dissociation energies
