| 6. | This approach has shown particular promise with the cobalt ( iii ) - salen - catalyzed hydrolytic kinetic resolution of chiral epoxides , a highly selective reaction of interest because of the versatility of epoxides as precursors to pharmaceutically important targets 因为多功能性的环氧化合物在医药上是重要目标分子的前体,这个方法在高选择性反应- -钴( iii ) -沙林试剂催化的手性环氧化合物的水解动力学拆分上特别引人注目。 |
| 7. | ( 2 ) two methods including one - step and two - step methods were used to modify the platinum electrode . in the two - step method , the experiment conditions were confirmed , namely after modified by nafion film , the electrode was dipped in saturated solution of co ( salen ) for 24h . the electric current would decrease if the dipping time were too long 2 .用两科,方法对电极进行co ( salen ) / nafion修饰,即“一步法”和“两步法” ,对“两步法”的实验条件进行了选择,即将电极表面先修饰好nafion膜后,再浸泡在co ( sa1en )饱和溶液中24h即可,时间再长则峰电流反而会减小。 |
