title: CuI-catalyzed cross-coupling of N-tosylhydrazones with terminal alkynes: synthesis of 1,3-disubstituted allenes.
abstract: A CuI-catalyzed synthesis of 1,3-disubstituted allenes from 1-alkynes by the reaction with various N-tosylhydrazones has been developed. This method, which uses readily available starting materials and is operationally simple, offers 1,3-disubstituted allenes in moderate to good yields. The reaction also tolerates various functional groups.
