2412.     ---------------.  [NEGISHI, R.]  Qualitative Consideration on the Mechanism of Synthesis of Higher Alcohols From Carbon Monoxide and Hydrogen and From Lower Alcohols.  II.  Mechanism for Secondary Alcohols and the Comparison of Different Mechanisms.  Rev. Phys. Chem. Japan, vol. 18, 1944, pp. 58-70; Chem. Abs., vol. 41, 1947, p. 4770.

        After discussing Fischer-Tropsch’s intermediate acid theory, Morgan and coworkers’ aldol condensation theory, and Frolich’s and Grave’s modifications of Guerbet’s direct dehydration theory, the author supports the last as the most probable mechanism of synthesis of higher alcohols from lower alcohols or from CO and H₂, with the concession that the aldol condensation may take place if aldehydes and ketones are formed during the synthesis as secondary reactions.
