Abstract

Experimental Section Reactions of Oximes with Th'+C104-. A general procedure was adopted. Solid Th*+C1O4- and the oxime in the mole ratio 2:l were placed under argon in a septum-capped flask into which 20 mL of acetonitrile was injected by syringe. The mixture was stirred for 48 h. In all cases, the dark purple color of T l P faded with time but did not entirely disappear. When reaction was carried out in the presence of 2,6-di-tert-butyl-4- ...
