The ligand, chloro(phenyl) glyoxime, was prepared according to the procedure reported previously.
31
5.0 g phenyl-glyoxime was re-ground in an agate mortar, and then it was
formed as a suspended mixture by the addition of a sufficient
amount of chloroform. Dried chlorine gas was passed through
the suspended mixture while being exposed to a beam of UV
radiation for 15 to 20min. At the end of the processes, a white
product was obtained. After completion of the chlorination,
air was passed through the product for half an hour to remove
excess chlorine.
