Pauson−Khand Reactions of Electron‐Deficient Alkenes
TL;DR: Despite the common perception that alkenes possessing electron-withdrawing groups are not adequate substrates for Pauson−Khand (PK) reactions, a number of successful examples of this reaction involving electron-deficient alkenses, such as α,β-unsaturated ketones, esters, nitriles, sulfoxides and sulfones, have been reported in recent years as discussed by the authors.

Preparation and use of tetra-n-butylammonium per-ruthenate (TBAP reagent) and tetra-n-propylammonium per-ruthenate (TPAP reagent) as new catalytic oxidants for alcohols
TL;DR: Tetra-n-butylammonium per-ruthenate (Bun4N)(RuO4) and tetra n-propylammonmonium (Prn4N), with N-methylmorpholine N-oxide, function as mild catalytic oxidants for the high yield conversion of alcohols to aldehydes and ketones and are competitive with more conventional reagents as mentioned in this paper.
