Conclusions

  1. 1.

    A study has been made of certain aspects of the behavior of the cyclopropyl thioethers under electron impact (EI) and chemical ionization.

  2. 2.

    The presence of the cyclopropane ring (CPR) gives rise to strong [M-alkene]+ ion peaks in the EI spectra of the aliphatic cyclopropyl ethers and [M-CH3]+, [M-C2H5]+, and [M-SH]+ ion peaks in the EI spectra of their aromatics analogs.

  3. 3.

    The [M + H]+ ions of the aromatic cyclopropyl thioethers eliminate an ArH molecule.

  4. 4.

    The presence of two Cl atoms in the CPR reduces the stability of the M+ and [M + H]+ ions, and largely determines their further fragmentation.
