## Abstract The reaction of 2‐methylenenorbornane with N‐bromosuccinimide produced a mixture of six monobromides in an overall yield of about 60%. By irradiation in the presence of benzoyl peroxide __exo__‐ and __endo__‐3‐bromo‐2‐methylenenorbornanes, 2‐bromomethylnorborn‐2‐ene, __Z__‐ and __E__‐2‐
Radical bromination of 4,5-dimethylthiazole (1) was carried out using different stoichiometries of N-bromosuccinimide in the presence of 2,2Ј-azobisisobutyronitrile. Mono-, tri-and tetrabromo compounds 2, 5, and 6 were obtained in good yields with regioselectivity while the dibromo derivatives 3 and
Oxidative removal of the dithioacetal group of several protected sugar and 2acylamido-Zdeoxy sugar dialkyl dithioacetals with N-bromosuccinimide in 97% aqueous acetone or 1: 1 (v/v) 2-methyl-2-propanol-acetone was compared with removal with mercury dichloride-mercury(I1) oxide or mercury dichloride-
