三臭化アンチモンによる2-メチル-2-ブタノールの脱水反応に対する有機電子供与体の影響

抄録

Effects of four different electron donors, i. e., tetrahydrofuran, dioxane, N, N-dimethylf ormamide, and dimethyl sulfoxide, on the dehydration of 2-methyl-2-butanol with antimony tribromide were examined. The participation order of these donors on the induction period of the dehydration was estimated to be roughly 0.4, while that on the over-all process of the dehydration ranged from 0.8 to 1.7 depending on the kind of donor added. On the basis of these results, the difference between the effect of the kinds of donor added on the induction period and the over-all process of dehydration is discussed.
