Mass spectrometry of some arylidene thioxobenzyl or thioxobiphenyloxoethyl thiazolidinone compounds

This paper reports the results of a comparative study of the electron impact mass spectrometry data for a series of previously synthetized 5‐arylidene‐3‐(4‐chloro‐benzyl)‐4‐thioxo‐thiazolidin‐2‐one, and 5‐arylidene‐3‐(2‐biphenyl‐4‐yl‐2‐oxo‐ethyl)‐4‐thioxo‐thiazolidin‐2‐one derivatives. Theoretical calculations of molecular mechanics, MOPAC‒AM1, were used to explain the fragmentations observed.
