The reaction of 2,3-dichloropropene (1) and different carbonyl compounds (2) with an excess of lithium powder (1:7 molar ratio) in the presence of a catalytic amount of 4,4'-di-tert-butylbiphenyl (5 mol %) in tetrahydrofuran at 0-degrees-C leads, after hydrolysis with aqueous hydrochloric acid, to the corresponding 1,4-diols in a Barbia-type process.
