Metalhydridereduction of a variety of α-[phenyl(or methyl)seleno]alkyl aryl ketones gives a mixture of threo- and erythro-β-aryl-β-hydroxyalkyl phenyl(or methyl)selenides by carbonyl reduction and 1-aryl-1-alkanol by the substitution of a phenyl(or methyl)seleno group with hydrogen. With all metalhydrides examined the formation of the threo-isomer always predominated. The addition of various metal
