Abstract:
Electrochemical oxidation of hexaalkyldisilanes in acetonitrile follows the activation mechanism with cleavage of the Si-Si bond in the overall two-electron process. Oxidation of hexamethyldisilane occurs at a potential 1 V more positive than the standard potential of the process. The standard potential of the leaving group Me3Si+/Me3Si is negative and large in value, which determines the activation character of the whole process. © 1999 MAHK "Hayka/Interperiodica".
