文摘Arylaldoxime dehydrodimers 3a—1 have been prepared from the corresponding oximes 1a—1 by using (HCrO_4)_2(Py)_4Co as oxidant.Their structures were assigned to be bisnitrone by XPS studies. ESR studies of 3a—1 in hot chloroform show that iminoxy radicals 2a—1 are formed.Therefore the dehydrodimers can provide a convenient source of these radicals.
