A variety of unsymmetrical 1,3-diynes can easily be accessed in good yields under catalyst- and transition metal-free conditions by reacting terminal alkynes with hypervalent iodine-based electrophilic alkyne-transfer reagents.

We show a facile method to prepare surface-clean monodispersed small and stable CuOx nanoparticles with controllable average sizes from below 1 nm up to ～5 nm without using bulk capping agent. Structural and surface characterizations show that the chemica

3, 3′-Disubstituted 2, 2′-binaphthyls were prepared by the Cuor Re-catalyzed double benzannulation reaction of 2-(phenylethynyl) benzaldehyde with various butadiynes in the presence of trichloroacetic acid, in moderate to good yields. Acceleration of the second benzannulation was clearly observed.
