Zirconium-mediated alkyene-aldehyde coupling, rhodium-catalyzed alkene hydrothiolation, and copper-catalyzed alkyne hydroarylation: Reaction development and mechanistic investigations
… undergo a rhodium-catalyzed regiodivergent hydrothiolation reaction to afford either 1,2- or 1,3-aminothioethers. The regiodivergence is a result of the ligand employed. Ligands with small bite angles afford the 1,3-isomer, while ligands with large bite angles afford the 1,2-isomer. …

Transition metal-catalyzed olefin functionalization for highly regio-, enantio-, and chemoselective C–X bond formation
… In chapter 1, a regiodivergent Rh-catalyzed hydrothiolation of allyl amines to form 1,2- or 1,3-aminothioethers with excellent degrees of regioselectivity is reported. Bidentate phosphine ligands with larger natural bite angles (βn ≥ 99°) promote a Markovnikov-selective hydrothiolation in up …

Reacciones de metátesis e hidrotiolación como herramientas sintéticas para la obtención de compuestos con interés biológico
… interest. For this purpose, metathesis and hydrothiolation reactions have been used as key steps. In the first part of this report, we performed a thorough study of the metathesis reaction on 7-azanorbornene systems. Ring rearrangement metathesis (RRM) in N-acyl-1-substituted-7-azanorbornene …

Iridium (III) photosensitisers for photoredox catalysed carboxylation reactions of ketimines
… of the visible light mediated regioselective hydrothiolation reaction of alkenes. The higher yields obtained for the hydrothiolation reaction was attributed to there being a greater driving force for electron transfer processes with the trinuclear complexes. In this study, a series of …

Synthesis and characterisation of small molecule and macromolecular photoredox catalysts for radical thiol-ene reactions
… evaluated as photoredox catalysts in the radical hydrothiolation reaction of olefins (thiol-ene reactions) to produce thioethers, which are valuable starting materials in the pharmaceutical industry, material and polymer science, and in the synthesis of various drug molecules. The isolated yields, …
