The reaction of NaNO2 in acidic solution with thiocarbonyl compounds has been studied.Secondary- and tertiary thioamides, 1-benzyl-hexahydro-2H-azepine-2-thione, 5-ethyl-5-phenyl thiobarbituric acid, certain thiourea derivatives, 2H-1-benzopyran-2-thione, O,O-diphenyl-thiocarbonic ester, O,S-diphenyl-dithiocarbonic ester, N,N-dimethyl-S-phenyl-dithiocarbamatic ester, N-ethyl-N-phenyl-O-ethyl-thiocarbamatic ester are all converted into the corresponding carbonyl-analogues. 4,4'-Bis(dimethylamino)-thiobenzophenone (Michler's thioketone) gives 3-nitro-4,4'-bis(dimethylamino)-benzophenone at room temperature.At (-10 deg C)-(-5 deg C) the expected oxo compound is obtained as the main product together with 4-(N-nitroso-methylamino)-4'-(dimethylamino)-benzophenone.
