## Abstract Oxone has been found to be a highly efficient reagent for the introduction of a hydroxy group at the α position of a variety of β‐dicarbonyl compounds in the homogeneous solvent mixture of water and 1,4‐dioxane at 60 °C.
The non-heme iron complex, Fe(TPAA = tris-[N-(2-pyridylmethyl)-2-aminoethyl]amine)(ClO 4 ) 2 , is a bad catalyst for the epoxidation of alkenes such as cyclooctene, cyclohexene and cis-stilbene and for the hydroxylation of alkanes such as adamantane by H 2 O 2 , when compared to the iron porphyrin F
