Abstract

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.
