A Pb/Al bimetal system was used to carry out reductive addition of tetrachloromethane, tetrabromomethane, bromotrichloromethane, trichloroacetamide, and trichloroacetonitrile to aldehydes. Subsequent 1,2-elimination of the halogen atom and hydroxyl group from the coupling products was also performed with the Pb/Al bimetal system. The technology was successfully applied to stereocontrolled syntheses of ethyl trans- and cis-3-(2,2-dihaloethenyl)-2,2-dimethylcyclopropanecarboxylates.
