The fragmentation mechanism for loss of XCY (X and Y = O or S) from 2‐phenyl‐1‐3‐4‐oxadiazole‐5‐one and related sulfur‐containing compounds begins with the breaking of the CN bond of the heterocyclic ring. Then a XCY molecule is ejected with the initial formation of a non‐rearranged ion. The major part of Δ H R 0 is associated with the stabilization of this neutral fragment. The initial fragment ion is further rearranged before it decomposes.
