The aminoxyl radical (>N-O.) BTNO (benzotriazole-N-oxyl) has been generated by the oxidation of 1-hydroxybenzotriazole (HBT; >N-OH) with a CeIV salt in MeCN. BTNO presents a broad absorption band with λmax 474 nm and e 184
Capto-dative Substituent Effects in Benzylic Radicals, II - Rotational Barrier in α-Cyano-α-methoxybenzyl Radical

The barrier to rotation about the benzylic bond in α-cyano-α-methoxybenzyl radical was determined to Ea = 9.8 +/- 0.8 kcal/mol (log A = 12.6 +/- 0.5) by ESR line-shape analysis in the temperature range from 30 to 80 deg C.Comparison with known and estimated rotational barries in α-monosubstituted benzyl radicals indicates for this radical no special captodative stabilization which exceeds the additivity of the substituent effects.
