Abstract

Ketones P 0200Ruthenium-Catalyzed Hydrative Dimerization of Allenes. -A new hydrative dimerization of allenes (I) (6 examples) using a combination of a ruthenium catalyst and a strong acid such as trifluoroacetic acid is described and a probable reaction mechanism is proposed. -(SAITO*, S.; DOBASHI, N.; WAKATSUKI, Y.; Chem.
