Abstract

Aldehydes react with hydrazoic acid and alcohols in the presence of catalytic amounts of TiCl₄ to produce α-azido ethers. The conversion of simple ketones to methyl α-azido alkyl ethers can be accomplished by means of hydrazoic acid and methyl orthoformate. Both gas-phase thermolysis and photolysis of representative a-azido ethers were studied and shown to produce mainly imino ethers. In the thermolysis, migratory preference decreases in the series H » CH₃ > Ph » OR.
