Abstract: The interaction of CH3Cl/CD3Cl or CH2Cl2/CD2Cl2 with the carborane acid H(CHB11Cl11) (abbreviated as H{Cl-11}) generates the salts of CH3-{Cl-11} and CH2Cl-{Cl-11} and their deuterio analogs, respectively, which are analogs of the salts of asymmetric chloronium cations. Next, salts of chloronium cations CH3-Cl+-CH3, ClCH2-Cl+-CH2Cl, and ClCH2-Cl+-CH3 and their deuterio analogs were obtained from the above compounds. The asymmetric ClCH2-Cl+-CH3 cation was found to be unstable, and at ambient temperature, slowly disproportionated into symmetric cations (CH3)(2)Cl+ and (CH2Cl)(2)Cl+. At a high temperature (150 degrees C), disproportionation was completed within 5 minutes, and the resulting cations further decomposed into CH3-{Cl-11} and CH2Cl-{Cl-11}. The molecular fragment ClCH2-(X) of the compounds (X = {Cl-11}, -Cl+-CH2Cl, or -Cl+-CH3) is involved in exchange reactions with CH2Cl2 and CHCl3, converting into CH3-(X) with the formation of chloroform and CCl4, respectively.
