Methanolysis of diazoalkynes
Abstract
The alkaline cleavage of N-nitroso-N-prop-2-ynylamides (1) and (9) in methanol and the photolysis of alkynone tosylhydrazones (4) and (10) in methanol–sodium methoxide afforded both allenyl and prop-2-ynyl methyl ethers; the site of protonation of diazopropynes and the reactivity of prop-2-ynyldiazonium ions have been investigated.
