The fragmentation of six substituted 10‐alkylphenothiazines is discussed. Predominant expulsion of OH, SO and O occurs from the molecular ions of 10‐alkylphenothiazine‐5‐oxide derivatives, the relative extent depending upon the configuration of the 10‐substituent. The simultaneous elimination of two OH radicals from the molecular ion of 10‐alkylphenothiazine‐5‐sulphone derivative is also observed.
