In situ trapping of reaction intermediates combined with stereochemical studies of the reaction of lithium dimethylcuprate with enones provides evidence for a pathway involving d,?*-cuprate-enone and copper(III) β-adducts as important intermediates in cuprate-mediated conjugate addition of carbon.

A series of Ru(II)/arene complexes containing N-alkylated derivatives of TsDPEN were prepared and tested in the asymmetric transfer hydrogenation (ATH) of ketones. The results demonstrated that a wide variety of functionality were tolerated on the basic amine of the TsDPEN ligand, without significantly disrupting the ability of the catalyst to catalyse hydrogen transfer reactions.
CATALYST AND PROCESS FOR SYNTHESISING THE SAME

Page/Page column 67; 68, (2014/05/24)
The invention relates to a method for synthesising tethered ruthenium catalysts and novel tethered ruthenium catalysts obtainable by this methods. The method involves carrying out an "arene swapping" reaction avoiding the requirement to use complicated techniques making use of unreliable Birch reductions and unstable cyclodienyl intermediates.
S,S'-Diethyl Dithiomalonate as Ethanol Carbanion Equivalent in Annelation Reactions
Liu, Hsing-Jang,Han, Yongxin
, p. 1484 - 1485 (2007/10/02)
S,S'-Diethyl dithiomalonate 1 undergoes concomitant alkylation reaction and Michael addition with ω-iodo-α,β-unsaturated ketones; the thiomalonate group present in the cyclization products can be easily reduced by Raney nickel to ethanol level.
