All 16 bromination products of phloroglucinol and its methyl ethers, as well as five bromoresorcinols and three of their dimethyl ethers, were synthesized and analyzed by nuclear magnetic resonance spectroscopy. Two or three equivalents of bromine convert phloroglucinol to di-and tribromophloroglucinol, 5-methoxyresorcinol to the tri-and 2, 4- dibromo, 3, 5-dimethoxyphenol to the tri-and 2, 6-dibromo, and 1, 3, 5-trimethoxybenzene ...
