With regard to the resolution of enantiomers, some applications can be found with modified silica gel supports. Thus, a Pirkle-type CSP was used for the separation of 200 mg of a racemic benzodiazepinone [75]. Also tris-(3,5-dimethylphenyl)carba-mate of cellulose coated on silica [91, 92] was applied successfully to the resolution of the enantiomers of 2-phenoxypropionic acid and to oxprenolol, alprenolol, propranolol among other basic drugs. However, the low efficiency of this technique and the relative high price of the CSPs limits its use to the resolution of milligram range of sample. 

A single o- or p-methyl substituent has no influence on the rate of cyclization of the singlet tolylnitrene to the favored azirine. ° The methyl group has no bystander effect on benzazirine formation. Cyclization of 2,6-dimethylphenyl or 2,4,6-tri-methylphenylnitrenes necessarily proceeds toward a carbon bearing a substituent. A steric effect raises the barrier to cyclization by 1.5-2.0 kcal/mol, in excellent agreement with the predictions of Karney and Borden. The steric effect extends the lifetime of 2,6-dimethylphenylnitrene at ambient temperature to 13 ns in Freon-113 and of 2,4,6-trimethylphenylnitrene to 8 ns, in the same solvent (Table 11.4). ° ...
