Abstract
Proton-donor properties of HCCl3, HSiCl3, and HGeCl3 molecules were studied by quantum-chemical methods. According to calculations, the Mulliken charge of H is positive in trichloromethane and negative in the other two molecules. Trichlorogermane readily interacts with bases (B) to give the contact ion pairs HB+·GeCl3 –. Reactions of trichlorosilane with strong bases also can lead to its reorganization and the formation of contact ion pairs. In all the ion pairs, the anions are oriented to the HB+ cations by the negatively charged Cl atoms. Owing to possible transfer of Cl– to HB+, this type of ion pairs can be a source of dichlorogermylene GeCl2 and, probably, dichlorosilylene SiCl2.
