Mass spectra of fourteen 2‐styryl‐ and 2,5‐distyrylfuran and ‐thiophene derivatives are reported. Each styryl substituent has an α‐carboxylic acid or methyl carboxylate substituent. Although the parent ion is the base peak for the styryl and distyryl derivatives, the distyryl species showed less fragmentation than the styryl species. In addition to simple bond cleavages, loss of formic acid or methyl formate was important in many of the species, presumably forming acetylenic fragments.
