Perfect to a THT! Screening a diverse library of thioether ligands led to the discovery of tetrahydrothiophene (THT) as a highly reactive and selective ligand for Pd-catalyzed allylic C-H oxidation reactions (see scheme). This novel ligand system provides some of the highest reported yields for the formation of (E)-linear allylic acetates through allylic C-H activation chemistry (BQ = 1,4-benzoquinone). Copyright

Alk-2-enylpotassium compounds having the endo conformation are synthetically very valuable precursors of (Z)-olefinic derivatives substituted at the outward allylic position. They may be generated by "stereoconservative" metalation of the readily available (Z)-alk-2-enes by using the superbasic mixture of butyllithium and potassium terf-butoxide or by metalation under similar conditions of stereorandom mixtures of alk-2-enes or alk-1-enes followed by torsional isomerization of the concomitantly formed exo conformers to the thermodynamically more stable endo species. The principal factors that dictate the rate and the extent of the endo/exo equilibration are the substrate geometry, the solvent, the temperature, the reagent stoichiometry, and catalysis Keywords: Torsional (ZIE) isomerization / Selectivity, regio- and stereo- / Allylsilanes / Allylic oxidation VCH Verlagsgescllschaft mbH.
