| Abstract | Oxidation o r scveral aliphat ic secondary alcohols by benzylt riethylammo nium chlorochromate in d imcthylsulrox ide leads to th e forma lion or correspondi ng kelones. Thc reacli on is rirst order each in benzyltri ethylammonium chlorochromate and the alcohols. The reaction is cata lyscd by hyd rogen i0ns. Hydrogcnion depe ndence has the ro rm: /.:ohs = (( + !J [I-I+J. The oxidation of benzhydrol-C'1-d ex hi bits a substantial primary kinelic isotope efrect (/.:I//.:D = 6.12 al 288 K). Oxidalion or 2-[1ro[1 anol has been studied in ni neleen d ilTerent orga nic so lvenls. The solvent elTeet h:15 been analysed using Ta rl 's and Swain 's Illu it iparalllelric eq ual ions. The reaclion has been subjec teu to both polar and ste ri c effects or the subsl ituel1ls. A mechani sm in volving tra nslCr or hyuride ion rrom alcohol to the ox id ant via a chromale ester is also proposcd. |
