TL;DR: In this article, the authors evaluated the performance of two different types of catalysts for asymmetric dihydroxylation of trans-stilbene, namely, Resin-OsO 4 and SiO 2 -OsO4, and showed consistent activity and enantioselectivity in asymmetric diolation using K 3 Fe(CN) 6 and molecular oxygen as cooxidants.

TL;DR: In this paper, a new bifunctional catalyst consisting of active palladium and osmium species anchored on silica gel through a mercaptopropyl spacer and a cinchona alkaloid respectively has been prepared for the first time and used in the heterogeneous tandem Heck-asymmetric dihydroxylation of olefins to afford diols with excellent yields and enantiomeric excesses.

TL;DR: In this article, a bifunctional catalysts composed of PdCl 4 2-, OsO 4 2 -, O4 2 - and O4 O 2 -Na 2 WO 4 with nanocrystalline MgO were proposed.

TL;DR: In this paper, a recoverable and reusable new heterogeneous AP-Mg-OsO4 catalyst was designed and developed for the first time via a counterionic stabilisation of OsO42- with Mg2+ present on the corner or edge of nanocrystalline MgO.

TL;DR: The PEG-scandium triflate catalyzed allylation of a variety of aldehydes and aldimines using polyethylene glycol (PEG) as a recyclable reaction medium proceeds smoothly and affords corresponding homoallylic alcohols and amines in good yields as mentioned in this paper.
