developed with special attention focussed on the applicability of the reaction. Sodiumalkoxide is used as the nucleophile, and the correspondingalcohol as the solvent. The reaction requires neither precious metals nor organic ligands. It uses a catalytic system consisting of copper(I) bromide as a catalyst, the corresponding alkyl formate as a noncontaminating cocatalyst, and lithium chloride as an additive
