Abstract: Alkylation of 1,3,5-trimethoxybenzene with 3,5-di-tert-butyl-6-methoxymethylcatechol affords new sterically hindered biscatechol, whose oxidation gives the corresponding bis-o-quinone. Its treatment with triphenylstibine leads to bis-triphenylantimony(v) bis-catecholate. read more here.

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.
