A one-pot reaction of diorganyl telluride, diazo-compounds including dimethyl diazomalonate and ethyl diazoacetate, carbonyl compound and catalytic amount of Cu(I)I afforded the olefination products in high yields. The reaction is proposed to be through diorganyltelluronium bis (methoxycarbonyl)methylide and (ethoxycarbonyl)methylide respectively.
