Chiral sulfoxides: advances in asymmetric synthesis and problems with the accurate determination of the stereochemical outcome.
Jianlin Han,Vadim A. Soloshonok,Vadim A. Soloshonok,Karel D. Klika,Józef Drabowicz,Alicja Wzorek,Alicja Wzorek +6 more
TL;DR: This work concerns a critical discussion of the problem of the accurate determination of the stereochemical outcome of a reaction due to the self-disproportionation of enantiomers (SDE) phenomenon, particularly as it relates to chiral sulfoxides.

Preparation and characterization of functionalized Cu(II) Schiff base complex on mesoporous MCM-41 and its application as effective catalyst for the oxidation of sulfides and oxidative coupling of thiols
TL;DR: An efficient and highly selective heterogeneous catalyst was prepared via immobilization of Cu(II) Schiff base complex on mesporous MCM-41, which is derived from 3,4-dihydroxybenzaldehyde and 3-amino propyl triethoxysilan as discussed by the authors.
