title: Cycloaddition reactions between dicyclohexylboron azide and alkynes.
abstract: The room temperature 1,3-dipolar cycloaddition reactions of the boron azide, Cy2BN3 with the electron-poor acetylenes RCO2C≡CCO2R, EtC≡CCOMe and HC≡CP(=O)Ph2 afforded new 1,2,3-triazoles. In the case of RCO2C≡CCO2R, a new macrocyclic product was isolated with loss of the R group.
