✦ Synopsis


The formation of the styryl ion PhCH=CH in the mass spectra of some cinnamic compounds is shown to occur via the intermediate formation of the cinnamoyl ion Ph-CH=CH-C=O rather than by direct cleavage of the bond CL to the double bond.

The methane negative-ion chemical ionization (NCI) mass spectrum of chlorprothixene shows an unusual MHion. This ion can be accounted for by electron capture followed by H transfer from the reagent gas. The most probable site of electron attachment was concluded to be related to the sulfur atom of t
