A metal-free synthetic protocol for N-vinylazoles has been developed. Twenty-two structurally diversed N-vinylazoles including 15 new compounds are obtained with good to high yield at near room temperature, and all of products consist trans-alkene moieties with high stereoselectivity.

Key words: metal-free, C—N coupling, vinylation, azoles, stereoselectivity
