V. Bansal et al., Kinetics and mechanism of the oxidation of substituted benzaldehydes by oxo(salen)manganese(v) complexes, J CHEM R-S, (8), 1999, pp. 480-481A
The oxidation of benzaldehyde by oxo(salen)manganese (v) complexes proceeds
via either a hydride-ion transfer or a hydrogen-atom transfer from the ald
ehyde to the manganese(v) complex.
