Zur Koordination Mehrfunktioneller Thioether in Cyclopentadienyleisen-Komplexen
Kuhn, Norbert,Schumann, Hans
, p. 93 - 104 (1986)
+ reacts with the ligands L-L and L-L-L to give the cations + (L-L= RS(CH2)nSR, 1,4-dithiane) and + (L-L-L= 1,3,5-trithiane, tris(methylmercapto)methane) containing monodentate coordinated sulfur ligands.In a similar way, sulfur ligand bridged dinuclear dications 2+ and 2+ and trinuclear trications 3+ are formed.Irradiation of the mononuclear cations gives the chelate complexes 2-L-L)>+.
A Bulky Disulfoxide Ligand for Pd-Catalyzed Oxidative Allylic C-H Amination with 2,2,2-Trichloroethyl Tosyl Carbamate

Challenging substrates and conditions in homogeneous catalysis pose stringent demands on the ligands used. A novel, bulky, 1-adamantyl-substituted disulfoxide ligand designed after a systematic evaluation of the electronic and steric properties of disulfoxide substituents permits the allylic oxidative C-N coupling reaction to proceed at lower catalyst loading while requiring a smaller excess of reagents. Additionally, this ligand improves the yields when TsNHCOOCH2CCl3, a novel reagent that permits deprotection of the products under both acidic and basic conditions, is used.
Molecular complexity via C-H activation: A dehydrogenative Diels-Alder reaction
Stang, Erik M.,White, M. Christina
supporting information; experimental part, p. 14892 - 14895 (2011/11/01)
Traditionally, C-H oxidation reactions install oxidized functionality onto a preformed molecular skeleton, resulting in a local molecular change. The use of C-H activation chemistry to construct complex molecular scaffolds is a new area with tremendous potential in synthesis. We report a Pd(II)/bis-sulfoxide- catalyzed dehydrogenative Diels-Alder reaction that converts simple terminal olefins into complex cycloadducts in a single operation.
Silica-promoted facile synthesis of thioesters and thioethers: A highly efficient, reusable and environmentally safe solid support
Basu, Basudeb,Paul, Susmita,Nanda, Ashis K.
experimental part, p. 767 - 771 (2010/09/05)
An efficient, mild and rapid procedure for the acylation and alkylation of aromatic and aliphatic thiols mediated on a silica gel surface at room temperature is described. The protocol allows the protection of thiols under neutral heterogeneous conditions without requiring any bases or Lewis acids, and the silica gel used as the promoter can be recycled for several runs without any loss of activity.
