Rk. Dieter et al., OXIDATION OF ALPHA,BETA-ENONES AND ALKENES WITH OXONE AND SODIUM-HALIDES - A CONVENIENT LABORATORY PREPARATION OF CHLORINE AND BROMINE, Tetrahedron letters, 37(14), 1996, pp. 2377-2380
Mixtures of oxone and sodium chloride or sodium bromide afford solutio
ns of chlorine or bromine, respectively. These solutions effectively a
dd chlorine and bromine to alpha,beta-enones and alkenes. The method a
ffords improved yields of 3-alkyl-2-halo-2-cycloalkenones which are so
metimes difficult to prepare. Copyright (C) 1996 Elsevier Science Ltd
