Photochemical nitration by tetranitromethane. Part XXXVII. Adduct formation and the regiochemistry of attack of trinitromethanide ion on radical cations in the photochemical reactions of 2-methyl-, 2,3-dimethyl- and 2,4-Dimethylanisoles

The photolysis of the charge transfer (CT) complex of tetranitromethane and 2-methylanisole 2 in dichloromethane at 20 °C gives the epimeric 1-methoxy-6-methyl-6-nitro-3-trinitromethylcyclohexa-1,4-dienes 8 and 9 in addition to 2-methyl-4-trinitromethylanisole (3) and 2-methyl-4-nitroanisole (4). In acetonitrile the yields of compound 4 and adducts 8 and 9 are significantly higher. Similar reaction of 2,3-dimethylanisole (6) in dichloromethane gave nitro-trinitromethyl adducts 10 and 11, hydroxy-trinitromethyl adducts 12 and 13, 2,3-dimethyl-5-trinitromethylanisole (14), 4-methoxy-2,3-dimethylbenzonitrile N-oxide (15), 2,3-dimethyl-4-trinitromethylanisole (16), 2,3-dimethyl-4-nitroanisole (17), 2,3-dimethyl-4,6-dinitrophenol (18), 3-methoxy-4,5-dimethyl-benzoic acid (19) and the hydroxy dinitro compound (20). The photolysis of the CT complex of 2,4-dimethylanisole (7) with tetranitromethane in dichloromethane gave the epimeric 1-methoxy-4,6-dimethyl-6-nitro-3-trinitromethylcyclohexa-1,4-dienes 21 and 22, together with 4,6-dimethyl-3-trinitromethylanisole (23), 4,6-dimethyl-2-nitrophenol (24), 4,6-dimethyl-2-trinitromethylanisole (25), 4,6-dimethyl-3-nitroanisole (26), 4,6-dimethyl-2-nitroanisole (27) and 4,6-dimethyl-4-nitrocyclohexa-2,5-dienone (28). The modes of formation of the above products are discussed, including the effects of the reaction solvent on those processes. The X-ray crystal structure of 1-methoxy-2-methyl-c-6-nitro-r-3-trinitromethylcyclohexa-1,4-diene (9) is reported. Acta Chemica Scandinavica 1997.

I. Photochemical nitration of methoxybenzenes from charge-transfer complexes with tetranitromethane

The direct irradiation of the charge-transfer (CT) absorption band of the 1/1 electron donor-acceptor complexes of dimethoxybenzenes with tetranitromethane leads to aromatic nitration with a high quantum yield.The analogous methoxytoluenes under the same photochemical conditions are converted in equally high yields to products of aromatic trinitromethylation.This dichotomy with different methoxybenzenes (ArH) is discussed within the context of the common reactive intermediates derived from the CT excitation of the complex.The subsequent interactions of the geminate fragments, i.e., +., C(NO2)3-, .NO2>, by radical-pair and ion-pair annihilation represent a unifying mechanism for the CT photochemistry leading to aromatic nitration and trinitromethylation.
