Abstract

Chemistry Chemistry, Organic Physical Sciences Science & Technology
The Cu+ catalyzed, 1,3-dipolar cycloaddition of polyoxyethylene di(azidoalkynes), yields a mixture of the polyoxyethylene 1,5-disubstituted fused di(1,2,3-triazole-1,4-oxazines) as the major product, and the 1,4-disubstituted mono-(1,2,3-triazolo) azidoalkyne crown ether.
