  名称：

  Catalytic Electrochemical Reduction of 1,2-Dibromocyclohexane Derivatives at Carbon Electrodes Modified with Cobalt Porphyrin Siloxane Films.

  摘要：

  The electrochemical reduction of trans-1,2-dibromocylohexanes is catalyzed effectively by Co(II) porphyrins at potentials greater than or equal to 1 V positive of the uncatalyzed case. With siloxane films on carbon electrodes containing a specially designed, diethylene glycol spacered Co-porphyrin, high catalytic currents are observed. Preparative current yields of 65% on a mmol scale are obtained with average calculated catalyst turnover numbers of ca. 5000.
