A supported copper hydroxide as an efficient, ligand-free, and heterogeneous precatalyst for 1,3-dipolar cycloadditions of organic azides to terminal alkynes.
英文:
A supported copper hydroxide as an efficient, ligand-free, and heterogeneous precatalyst for 1,3-dipolar cycloadditions of organic azides to terminal alkynes.
The supported copper hydroxide Cu(OH)x/Al2O3 acts as an efficient heterogeneous precatalyst for the 1,3-dipolar cycloaddn. of org. azides to terminal alkynes. The recovered Cu(OH)x/Al2O3 retains its high activity and can be reused. [on SciFinder(R)]
