Tetrasubstituted cyclopentadienones as suitable enantiopure ligands with axial chirality
Prati,Mancinelli,Ciogli,Mazzanti
, p. 8720 - 8728 (2017)
A series of thermally stable atropisomeric phencyclone ligands (ΔG?rac > 35 kcal mol-1), bearing two chiral axes, has been successfully synthesized, taking into account the results of DFT calculations on model systems. The absolute configurations of the novel atropisomers have been assigned using TD-DFT simulation of ECD spectra. Atropisomeric phencyclones herein presented pave the way towards new ruthenium-based enantioselective hydrogenation catalysts.

The unique structure of oxyallyls represents a significant challenge for their catalytic asymmetric applications. Herein, an unprecedented chiral imidodiphosphoric acid-catalytic enantioselective (3 + 3) cycloaddition between oxyallyl zwitterions generate
New Electrochemical Synthesis of Ketones from Organic Halides and Carbon Monoxide
Ocafrain, Maitena,Devaud, Marguerite,Troupel, Michel,Perichon, Jacques
, p. 2331 - 2332 (2007/10/02)
The dissolution of a stainless steel anode provides catalytic nickel species which enable the efficient synthesis of ketones by electrolysis of organic halides in DMF in the presence of bipyridine and carbon monoxide.
