Characterization of Organic Tin C ompounds by Mass Spectrometry

Abstract

In-beam electron impact ionization, isobutane chemical ionization and field desorption mass spectrometry were applied for the characterization of organic tin compounds.
In these compounds, primary cleavages of the Sn-C, Sn-X, S n-O and Sn-S bonds took place prior to other reactions so that the analysis of their mass spectra was relatively simple. The ten isotopes of the tin atom gave the information whether a fragment ion con tained tin or not.
Moreo ver, the kind and the distribution of alkyl or carboxyl group attached directly to the tin atom were easily determined from their mass spectral cracking pattern.
