Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Esters of alkoxypicolinic and alkoxynicotinic acids are reliably identified by means of their mass spectra and PMR spectra. While the alkoxypyridoyl cation in the case of the Β esters undergoes fragmentation only with the successive splitting out of an olefin via the McLafferty mechanism and then a CO molecule, these processes also take place in the reverse order in the case of the α esters. The principal characteristic fragment ions by means of which such compounds in liquid-crystal mixtures can be identified and quantitatively determined were established.
