Autor: Bernard Feringa, Marcel Lubben
Publikováno v: ChemInform. 25
Monoaminomethylated phenols 5-7 and symmetrically diaminomethylated phenols 8 and 9 were prepared in a one-step procedure-from p-cresol, formaldehyde, and a variety of secondary amines by making use of the aromatic Mannich reaction. Nonsymmetric diam

Catalytic Oxidation with a Non-Heme Iron Complex That Generates a Low-Spin FeIIIOOH Intermediate
Autor: Marcel Lubben, Gerard Roelfes, Ronald Hage, Ben L. Feringa, Lawrence Que
Publikováno v: Chemistry, 6(12). Wiley-VCH Verlag GmbH & Co. KGaA
The antitumor drug bleomycin (BLM) is proposed to act via a low-spin iron(III) hydroperoxide intermediate called "activated bleomycin". To gain more insight into the mechanistic aspects of catalytic oxidation by these intermediates we have studied th
