Reductive Addition of Polyhalomethanes and Their Related Compounds to Aldehydes and 1,2-Elimination of the Coupling Products in a Pb/Al Bimetal Redox System

Tanaka, Hideo,Yamashita, Shiro,Yamanoue, Motoi,Torii, Sigeru

, p. 444 - 450 (1989)

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.
