✦ Synopsis

The correlations between electron impact induced formation of fragment [M -C,&]+' from alkylsubstituted 2,2-diphenyl-1,3-dioxa-2-gennacyclohexane (1) and the peculiarities of the molecular structures were found. Benzene elimination is regiospecific and stereoselective, resulting from the abstraction of an axial phenyl group and a hydrogen atom from the C-4 or C-6 position of the ring.

## Abstract The mass spectra of 20 1,3‐dithianes were studied. The fragmentation patterns including the loss of 74 u and 107 u and clearage of the substituent at C‐2 depended strongly on the nature of the substituents at that position. 2,2‐Diphenyl‐1,3‐dithiane undergoes an atypical fragmentation i

A study of the fragmentation of 1-methyl-3-(2-benzothiazolyllhydrazono)-2-indolinone on electron impact reveals that the major processes involve N-N bond fission and the competing loss of CO from the molecular ion.
