Sažetak
The solvolysis of 3,3-di-tert-butyl-4-hvdroxyphenyl triflate (7) in tri- fluoroethanol buffered with the non-nucleophilic base, 2,G-di-tert-butyl-4-methylpyridine proceeds surprisingly fast. This phenomenon is explained by a new type of elimination of triflinate anion from the conjugate base 10 of the triflate 7 to form 2,6-di-tert-butyl-1,4-benzoquinone.
