Abstract

Variously substituted arylazides, as well as p-tosylazide, when allowed to react at room temperature with THF previously treated with n-butyllithium, undergo a rapid decomposition affording the corresponding amines and fomamides, together with diazomethane. This diazo transfer (with deformylation) reaction is thought to involve the enolate of the acetaldehyde generated by the known cycloreversion of THF in the presence on n
