In the presence of iron(II) sulfate, /cH-butyl hydroperoxide decomposes to yield acetone and methyl radicals, For a discussion of the kinetics and mechanism of purine C8 methylation by methyl radicals see ref 50. Reaction of adenine with benzenediazonium ions yields ( )-6-(3-phenyl-2-triazen-l-yl)purinc (7, Ar = Ph), which undergoes a C-arylation reaction, probably involving an intermolecular free-radical substitution at C8, to give 8.

AMMONIUM FERROUS SULFATE (10045-89-3) Reacts violently with reducing agents, acrolein, alcohols, chlorine trifiuoride, ethers, fluorine, hydrazine, hydrazinium perchlorate, hydrogen peroxide, finely divided aluminum or magnesium, ammonium perchlorate, mercury(II) dinitrate, peroxyfuroic acid, sodium acetylide, tetranitromethane. Sensitizes most organic azides that are unstable shock and heatexplosives. Forms explosive materials with l,3-di(5-tetrazoyl)triazene. Incompatible with glycidol, isopropyl chlorocarbonate, ni-trosyl perchlorate, sodium borohydride.

To a stirred solution of heteroarene (2 0.4 mmol) in dichloromethane (1.5 mL) at ambient temperature under open-flask was added TFA (0.32 mL) and triazene (1 0.6 mmol), the mixture was then stirred vigorously for 5 min. Then water (1.5 mL) and silver nitrate solution (20 mol % in 1.0 mL water) and potassium persulfate (0.32 g) was added successively, and the stirring was continued up to 24 h (TLC monitored). Upon completion of the reaction, 2N NaOH was added to quench excess TFA, extracted with dichlorometahne (5 x 20 mL), and dried over anhydrous sodium sulfate. Solvent was evaporated under reduced pressure and the crude residue was purified by silica gel flash chromatography (10% MeOH in CH2CI2) to furnish pure substituted het-eroaren 3, characterized by means of spectral studies.
