摘要

Co (Salpr), a five-coordinate cobalt (I1) Schiff base complex, has been found to promote oxygenation of 2, 6-di-tert-butylphenols bearing an electron-withdrawing group in the 4- position, leading to dioxygen incorporation exclusively into the ortho position of the phenols. 4-Acyl-2, 6-di-tert-butylphenols (1) and their oxime 0-methyl ethers (2) gave the corresponding 6-hydroperoxy-2, 4-cyclohexadienone derivatives 3 and 4 quantitatively. ...
