Mass spectrometric synthesis. V, The gas-phase ion-molecule dimerization of some sulfur containing heterocycles

The gas-phase, ion-molecule reactions occurring in the ion source of a mass spectrometer between differently substituted thiazoles, employed as starting compounds for synthesis of polymers exhibiting semiconducting properties, have been studied in detail. The structural characterization of the dimeric moieties so obtained has been carried out by exact mass measurements, linked scans for metastable analysis and collisional spectroscopy.
