Abstract

Abstract: Alkyl radicals are readily oxidized by the tris (phenanthro1ine) and tris (bipyridine) complexes ML, j+ of iron (III), ruthenium (III), and osmium (II1) in acetonitrile solution, the second-order rate constants easily exceeding IO6 M-'s-'at 25" C. Two oxidative processes are identified as (a) ligand substitution on the coordinated 1, lO-phenanthroline to yield various alkylphenanthrolines and (b) cation formation to afford alkenes and N- ...
