  Abstract:   Duff formylation of bis-(10-methylphenothiazin-3-yl)-methane obtained by the condensation of phenothiazine with formaldehyde was attempted. Theoretical data based on Density Functional Theory were used in order to explain the reduced reactivity of this substrate, as compared to parent 10-methylphenothiazine. Structural assignments were based on NMR spectroscopy.
