Abstract
Nine semifluorinated alkanes, F(CF2)n(CH2)mH, were analysed by electro n ionization and electron-capture mass spectrometry. Both techniques s howed the presence of H ... F bridges between the zigzag hydrocarbon c hain and the twisted fluorocarbon one. In particular, this interaction can explain the extensive sequential HF losses detected in electron-c apture mass spectrometry. The low abundance of fragments corresponding to cleavage of a CF2-CH2 bond indicate a relatively high bond strengt h.
