Abstract

Methyltris(triphenylphosphine)cobalt catalyses the aldol condensation of acetone and ethyl methyl ketone. From acetone mesityl oxide is obtained in ∼70% yield, while from ethyl methyl ketone 3-methyl-2-heptene-5-one and 3-methyl-3-heptene-5-one are formed in equal amounts in a total yield of about 100%. The latter products are known to be those of base-catalysed aldol condensation. The corresponding aldols are also observed in small quantities. The reactions mostly take place in the absence of solvent.
