The dicopper-substituted γ-Keggin silicotungstate (TBA) 4[γ-H2SiW10O36Cu 2II(μ-1,1-N3)2] (I, TBA = tetra-n-butylammonium) could act as an efficient precatalyst for the chemoselective cylopropanation of olefins with diazo compounds. Various kinds of olefins were efficiently converted to the corresponding cyclopropane derivatives in good yields.
