Treatment of 2,6-disubstituted-4-t-butylphenols with thallium(III) trifluoroacetate in either trifluoroacetic acid or carbon tetrachloride as solvent results in loss of the 4-t-butyl substituent as isobutene and formation in high yield of the corresponding 2,6-disubstituted p-quinones. Possible mechanisms for this novel reaction, which probably proceeds via the intermediacy of a hydroquinone or hydroquinone
用三氟乙酸th(III)在三氟乙酸或四氯化碳中作为溶剂处理2,6-二取代的4-叔丁基苯酚会导致4-叔丁基取代基作为异丁烯的损失并生成高产率的相应2 ,6-二取代对-醌。讨论了可能通过对苯二酚或对苯二酚单三氟乙酸酯的中间体进行的这种新反应的可能机理。由于这些机理上的考虑,三氟乙酸al(III)被证明是将氢醌和各种2,4,6-三取代的苯酚转化为相应的对苯醌的高效氧化剂。
