K. Ganesan,C.N. Pillai +1 more
TL;DR: In this paper, the reactions of acetophenone with methanol over η-alumina at 300-500 °C were studied, and the effect of acidity on the selectivity for these reactions was found to increase with increasing catalyst basicity.

New aspects of the transfer hydrogenation of α,β-unsaturated ketones by alcohols in the presence of hydridotetrakis(triphenylphosphine)rhodium(I): Part III. Kinetic equations and rate constant determinations
TL;DR: From the general scheme of the transfer hydrogenation of α,β-unsaturated ketones by alcohols in the presence of catalytic amounts of RhH-(PPh 3 ) 4, kinetic equations have been established which account for the various reaction intermediates as mentioned in this paper.

Catalytic conversion of alcohols: XXVIII. Product selectivities for 2-methylcyclohexanol conversion with metal oxide catalysts
TL;DR: In this article, the same catalytic properties determine the selectivity for both reactants: for smaller metal cations the product selectivity is determined by steric crowding in the transition state, and for the larger cations, product selectivities are determined by the basicity of the oxygen anion and the relative acidity of β-hydrogens that are eliminated to produce water.

Dehydrogenation of alcohols and hydrogen transfer from alcohols to ketones over hydroxyapatite catalysts
Charles L. Kibby,W.Keith Hall +1 more
TL;DR: In this article, the same authors reported the kinetic data for the dehydrogenation of 2-butanol and hydrogen transfer from this alcohol to 3-pentanone over the same catalysts, showing that both reactions occur on the same sites and involve the same intermediate species.
