fluorosilanes were obtained by direct CuF 2 ·2H 2 O/CCl 4 promoted fluorination of the corresponding hydrosilanes. Electrochemical oxidation potentials of sila-functional α-heteroatom-substituted organosiliconcompounds were determined. The introduction of a hydrogen or a fluorine substituent on the silicon caused a small increase in the oxidation potentials, which is consistent with the results of molecular
