Rates and products of electrophilic bromination of ring-substituted cis- and trans-stilbenes have been investigated in acetic acid, trifluoroethanol, ethanol, methanol, and water-methanol mixtures. The mY(Br) relationships (linear for nucleophilic solvent
Photolytic Dehydrochlorination of N-Chloro-N-alkyl Amides: Formaton of N-(α-Methoxyalkyl) Amides

The photoinduced dehydrochlorination, in methanol, of N-chloro-N-alkyl amides with one substitient at the α position to nitrogen gave good yields of N-(α-methoxyalkyl) amides and the parent amides as secondary products.N-Chloro amides disubstituted at the α position gave mostly parent amides.In most cases no products resulting from 1,5 hydrogen transfer of amidyl radicals were observed.The quantum yields of decomposition of N-chloro-N-methylpentanamide (1a) were significantly greater than unity, indicative of a chain process for dehydrochlorination.The reaction was affected by the solvent, addition of base or radical inhibitors, concentration of N-chloro amide, light intensity, and irradiation wavelenght.
