Abstract: The trans-etherification of 4,6-di-tert-butyl-2,3-dihydroxybenzyl methyl ether with α,ω-alkanediols under mild conditions (CHCl3, 65 °C) leads to new sterically hindered biscatechols in high yields. The molecular structures of three of them was determined by single-crystal X-ray diffraction. read more here.
