Abstract

1-(a-Alkoxyalky1) benzotriazoles deriving from aldehydes (other than formaldehyde), or from ketones, react with Grignard reagents at 110 “C to provide a high-yielding, general synthesis of dialkyl and alkyl aryl ethers. Under similar conditions, 1-(alkoxymethy1)-and 1-((ary1oxy) methyl) benzotriazoles give, by a different cleavage pattern of the NC-0 grouping, 1- alkylbenzotriazoles and N, N'-dialkyl-o-phenylenediamines. The 1-(a-alkoxyalky1) ...
