Arylaldoxime dehydrodimers 3a—1 have been prepared from the corresponding oximes 1a—1 by using (HCrO 4 ) 2 (Py) 4 Co 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.
