Scholarcy highlights

  • Detailed facts of importance to specialist readers are published as ”Supporting Information”
  • Quick click on solid catalysts: Supported copper hydroxide on titanium oxide can act as an efficient heterogeneous catalyst for the 1,3-dipolar cycloaddition of various organic azides to terminal alkynes
  • The observed catalysis was truly heterogeneous and the catalyst retrieved after the reaction could be reused at least three times with retention of its high catalytic performance
  • The observed catalysis was truly heterogeneous and the retrieved catalyst after the reaction could be reused at least three times with retention of its high catalytic performance. It was confirmed by the UV/Vis spectrum of Cu(OH)x/TiO2 and the amount of diyne formed that the CuII species in Cu(OH)x/TiO2 were reduced to CuI species by the alkyne–alkyne homocoupling at the initial stage of the reaction
  • The catalytic reaction rate for the 1,3-dipolar cycloaddition linearly increased with an increase in the amount of in situ generated CuI species
