(1) Thiocarboxylate anions [RCOS] − formed by dissociative secondary electron capture are either stable or fragment to yield [R] − . (2) Thiocarboxylate cations [RCOS] + formed by charge stripping from [RCOS] − , fragment to form [R] + , [COS] +. and [RCO] + (not when R=CF 3 ). (3) Aryl hydrogen scrambling is observed in the case of the thiobenzoate cation. Aliphatic hydrogen scrambling is not detected for the thiopropionate cation.
