Properties and Synthetic Utility ofN-Substituted Benzotriazoles

“…Benzotriazole, or its silver or mercury salt, or 1-(trimethylsilyl)benzotriazole, reacts with acetylated sugar halides such as tetra- O -acetyl-β- d -glucopyranosyl halides, − per- O -acetyl monosaccharide halides, , acetylated glycosyl halides, − and 1-bromo-1-methoxy-aldehydo- d -galactose pentaacetate to give the corresponding benzotriazole derivatives. The silver and mercury ions function as halide acceptors.…”
