✦ Synopsis

Abstract

The mass spectra of alkyl‐ and chloropyrimidines are recorded. A generalised fragmentation mechanism for the derivatives of pyrimidine is proposed. The principle of α‐cleavage for heterocyclic compounds as proposed in the previous paper is shown to be valid for pyrimidine derivatives. Electronic structures of some molecular and intermediate ions are calculated by the openshell CNDO/2 and INDO methods.

## Abstract It has been found by mass spectrometric studies that the so‐called ‘1:1‐adduct’ formed by N‐( __n__butyl)maleimide and benzaldazine, is in fact a solid mixture of one part __bis__‐imide L and one part benzaldazine. __Bis__‐imide L is one of the three stereoisomeric products obtained by

A mass spectrometric study of several tricarbonyl (h 6 -phenyl methanols) of chromium( 0) was performed. Electron ionization (EI), chemical ionization (CI) and fast atom bombardment (FAB) mass spectra were acquired for each molecule, and compared in order to establish a general fragmentation pattern

## Abstract The mass spectra of 2‐nitrosophenols are independent of the insertion temperature, suggesting that the compounds either do not exhibit tautomerism in the vapour phase or that the enthalpy of isomerization is low. However, their fragmentation patterns suggest tautomerism in the molecular
