ORGANOMANGANESE (II) REAGENTS XVIII: COPPER-CATALYZED 1,4-ADDITION OF ORGANOMANGANESE CHLORIDE COMPOUNDS TO CONJUGATED ETHYLENIC ALDEHYDES.
Cahiez, Gerard,Alami, Mouad
, p. 7365 - 7368 (1989)
Organomanganese chlorides react with β-mono or β,β-bisubstituted α,β-ethylenic aldehydes in the presence of a catalytic amount of copper chloride to give good yields of 1,4-addition products in THF at -30 deg C.
