The electron impact mass spectra of twelve thiazolidines have been measured and the fragmentation patterns examined. The three most intense fragmentations common to all the thiazolidines examined are: (a) the cleavage of the substituent at C‐2, (b) 1,4‐ring cleavage, and (c) 2,5‐ring cleavage. The 1,4‐ and 2,5‐cleavages occur with and without rearrangement of a proton.
