H–D exchange, configurational isomerization, and hydrogenolysis of 1,2-dimethylsilacycloalkanes on copper

The hitherto unreported H–D exchange, configurational isomerization, and hydrogenolysis of Z- and E-1,2-dimethylsilacycloalkanes on copper have been studied, and evidence has been obtained for the first time that copper is able to catalyse configurational isomerization.
