By using α-deuteriated substrate, it was established that in the thermal lead tetraacetate reaction (in benzene) of 5,5-dimethyl-2-heptanol (1) oxidation to the corresponding ketone 4 proceeds not only by way of direct elimination of the carbinol (α) hydrogen, but also, to the extent of 43·-5%, by a route which involves 1,5-transfer of hydrogen from the carbinol (α) carbon atom to the ϵ-C atom.
通过使用α-氘化的底物,可以确定,在5,5-二甲基-2-庚醇(1)的热四乙酸铅反应中(在苯中),氧化成相应的酮4的方式不仅是直接消除了甲醇(α)氢,但也可通过涉及氢从甲醇(α)碳原子向1-C原子的1,5-转移的途径达到43.-5%的程度。
