The major fragmentation pattern obsrved in the mass spectra of simple alkane‐ and arylsulfonyl chlorides may be rationalized by loss of a chlorine atom from the molecular ion, followed by loss of SO 2 with concomitant carbocation formation. The mass spectra of α‐mesyl sulfonyl chlorides and napthalenesulfonyl chlorides exhibit ions resulting from chlorine atom migration to the α‐carbon atom with concomitant loss of SO 2 . The mass spectra of α‐mesyl sulfonyl chlorides also show ions which involve chlorine atom migration to the β‐sulfonyl group.
