Shape-selective interception by hydrocarbons of the O2-derived oxidant of a biomimetic nonheme iron complex.
Picky ferryl: The complex [Fe(Tp(Ph(2)))(BF)] (Tp(Ph(2)) = hydrotris(3,5-diphenylpyrazolyl)borate; BF = benzoylformate) reacts with O(2) to generate an oxidant (see picture; O red, pink; Fe yellow; N blue; C gray; H white) that oxidizes added hydrocarbons shape-selectively. Discrimination derives from a cleft formed by two phenyl groups of the Tp(Ph(2)) ligand, favoring oblate spheroidal substrates.
