The thioacetanilide negative molecular ion (produced by secondary electron capture) is stable, but it fragments after collisional activation to yield [C 6 H 5 NH] − by cleavage α to the CS grouping. The negative molecular ions of (substituted) o ‐nitrothioacetanilides undergo a series of extremely complex rearrangement reactions. For example, the molecular anion derived from o ‐nitro‐ N ‐methylthioacetanilide yields both acetate and thioacetate anions as major fragment ions.
