Abstract: The invention relates to novel, scalable synthetic routes that allow for direct reduction of enones to the corresponding saturated alcohols. The invention relates, in certain aspects, to synthetic routes that allow for the reduction of enones to the corresponding ketones. Such reactions take place under mild conditions, are compatible with a wide range of functional groups, and expand the repertoire of existing green chemistry methodology. In certain embodiments, the reactions are run in aqueous solvent.

Abstract: Process for the continuous production of an optically active carbonyl compound by asymmetric hydrogenation of a prochiral α,β-unsaturated carbonyl compound with hydrogen in the presence of a homogeneous rhodium catalyst that has at least one chiral ligand, wherein a liquid reaction mixture comprising the prochiral α,β-unsaturated carbonyl compound is subjected in a first, backmixed reactor to a gas/liquid two-phase hydrogenation, and the liquid reaction mixture is then further hydrogenated in a second reactor, wherein the prochiral α,β-unsaturated carbonyl compound is employed in the first reactor in a concentration from 3% to 20% by weight. The process allows a high total conversion to the prochiral α,β-unsaturated carbonyl compound.

Abstract: A long-life catalyst which can be easily and inexpensively manufactured and has high activity and suppressed leakage of metal. A catalyst according to some embodiments includes: a substrate; and a first metal atom as a catalytic center. The substrate contains a non-metallic atom and a second metal atom, and the non-metallic atom is any one selected from the group consisting of a group 15 element, a group 16 element and a group 17 element.
