Baraldi, Pier Giovanni,Pineda de las Infantas, Maria J.,Manfredini, Stefano,Romagnoli, Romano
, p. 72 - 74 (2007/10/03)
4-Aryl-substituted-6-methyl-4H-pyrazolo[3,4-c]-1,2,5-oxadiazoles 15-21 were easily obtained through the oxidation reaction mediated by lead(IV) acetate of 5-methyl-4-nitroso-2-phenyl-2H-pyrazol-3-ylamines 8-14 in 88-97 percent yields.
