摘要

2, 7-Dimethyl-1, 8-biphenylenediol has been synthesized from 2-methyl-5-nitrophenol in nine steps. 1, 5-Biphenylenediol has been prepared by dimerization of 3-methoxybenzyne, separation of isomers, and demethylation. 8-Methoxy-1-biphenylenol has been made by the partial demethylation of 1, 8-dimethoxybiphenylene. Ionization constants (pK1 8.04, pK, 11.47, pKl 8.35, pK2 9.97, and pK 9.15, respectively) have been determined for these ...
