✦ Synopsis

In the electron impact mass spectra of some 2-thiouridines a prominent base +41 (b+C,HO) peak was found. The sulphur atom at the 2 position facilitates its formation.

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.
