And Chemical Properties

The oxidation reactions of heterobicyclic sulfides derived from α-thioglycerol (alkyl-2,8-dioxa-6-thiabicyclo[3.2.1]octanes), leading to sulfoxides and the corresponding sulfones, have been studied. The stereochemistry of the oxidation as a function of the reagent used (H2O2, meta-chloroperbenzoic acid, and tert-butyl hypochlorite) has been examined. Structural assignments of the sulfoxides arise from the spectroscopic and chemical properties of these compounds. [Journal translation]

Steric Influence

We evaluate the balance of steric and electronic effects in the site selectivity of the binding of [Rh(Me5Cp)]+ ([RhCp·]+) to the three possible coordination sites of the polyaromatic hydrocarbon (PAH) hexa-tert-butyl-hexa-peri-hexabenzocoronene (HBBC). We find that despite the close proximity of sterically demanding tert-butyl groups to the methyl groups of the Cp* ligand, the extent of steric repulsion is minor compared to electronic interaction from bond formation and that the site selectivity is best explained in terms of the electronics of the (poly) aromatic system. This is in contrast to previous investigations on similar systems with a COD ligand where steric influence has been shown to dominate selectivity.
