Abstract

The cyclic sulfenic ester 1,2‐oxathiolane (1) decomposes thermally (400 – 450 K) exclusively to give acrolein (3) via 3‐mercaptopropanal (2) by loss of hydrogen sulfide. Isotopic labelling experiments reveal the presence of a 1,2‐oxathiolane‐thietane 1‐oxide equilibrium (1 ⇌ 4).

Methylphenidate undergoes partial thermal decomposition in the injection port of a gas chromatograph. This decomposition explaiqs inconsistencies in some of the previously published mass spectra of the drug. The decomposition products were identified by gas chromatography mass spectrometry as methyl

## Abstract The unimolecular fragmentations of singly and doubly protonated __ortho‐__, __meta‐__, and __para‐__benzoquinones (BQH^+^ and BQH~2~^2+^, respectively) are studied by tandem mass spectrometry. The dominant fragmentation pathways lead to the elimination of a neutral CO molecule from BQH^
