Under homoenolization conditions (t-BuO−, t-BuOH, 185 °C), 7,7-dimethyltricyclo[3.2.1.02,4]octan-6-one (5) readily rearranges to 4,4-dimethyltricyclo[3.3.0.02,8]octan-3-one (6) which subsequently suffers reduction of the three-membered ring, presumably by electron transfer from the tert-butoxide anion for which some evidence has been obtained. The conversion of 5 to 6 constitutes one of very few examples of rearrangement via a γ-enolate. From reactions in tert-butyl alcohol-O-d1, deuterium incorporation at the several sites in 5 and 6 undergoing H/D exchange was directly monitored by 2Hmr spectroscopy; these results shed light on the stereochemistry of homoenolate formation and cleavage.

Kinetics Of

The kinetics of oxidation of [Co(en)2SCH2COO]+ with S2O82- was studied in water-methanol and water-tert-butyl alcohol mixtures. Changes in the reaction activation parameters ∆H≠ and ∆S≠ with varying concentration of the co-solvent depend on the kind of the latter, which points to a significant role of salvation effects. The solvation effect on the reaction is discussed based on a comparison of the transfer functions ∆Ht0, ∆St0 and ∆Gt0 for the initial and transition states with the changes in the activation parameters accompanying changes in the CO-solvent concentration. The transfer enthalpies of the reactant were obtained from calorimetric measurements.
