Conclusions The Wurtz reaction can be interrupted at the intermediate organo-metallic stage if the alkyl halide is added to excess sodium at low or moderate temperatures. The reaction has been studied in some detail with n-amyl chloride and has been tested in a preliminary way with a number of other organic halides. In the case of n-amyl chloride, caproic and butylmalonic acids were obtained upon carbonation. The yield of combined acids in one ...
