Abstract
The mass spectrometry behaviour of dimethylaminomethyl- and α-(dimethylamino)ethyl derivatives of cymantrene and ferrocene, their iodine methylates as well as of the deutero analogues of these compounds has been studied. It has been shown that mass spectrometry can be successfully employed for the quantitative determination of the total deuterium content in aminoalkyl derivatives of cymantrene and ferrocene, the distribution of the label between the dimethylaminoalkyl group and the metallocenyl fragment and in case of the dimethylaminomethylferrocene also between the substituted and unsubstituted cyclopentadienyl rings. The data on the distribution of the isotopic label were used to ascertain the mechanism of fragmentation of the dimethylaminomethylferrocene under electron impact.
