Mass spectra of thiazolidines

Abstract
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.
