NaCH3COO in dichloromethane; water a soln. of Mn-compd. in CH2Cl2 was treated with a dil. aq. soln. of NaCH3COO; the procedure was repeated, followed by a final wash with distd. water; the org.layer was collected, dried over anhyd. Na2SO4, then reduced to 5 ml under reduced pressure;; crystn. by slow addn. of heptane; purity was confirmed by visible spectroscopy and cyclic voltammetric behavior;;

in 2-methyl tetrahydrofuran Irradiation (UV/VIS); photoredn. of the Mn(III) complex in MeTHF by irradiation with visible light (440-750 nm) at 25°C; not isolated; detn. by UV/VIS spectral change;

in methanol byproducts: H2; reduced with NaBH4 in methanol; not isolated, detected by UV;
