Abstract 2, 3, 4, 5, 6-Pentabromobenzyl bromide reacts with primary and secondary alcohols and also with alkali metal alkoxides derived from primary alcohols to form the corresponding pentabromobenzyl ethers in high yields. In the reactions with secondary alkoxides, considerable amounts of bis (2, 3, 4, 5, 6-pentabromobenzyl) ether are formed.
