Rh(I)/(III)-N-Heterocyclic Carbene Complexes: Effect of Steric Confinement Upon Immobilization on Regio- and Stereoselectivity in the Hydrosilylation of Alkynes

<p>Novel Rh(III) pentamethylcyclopentadienyl and Rh(I) complexes containing chelating N-heterocyclic carbenes have been prepared and used in the hydrosilylation of 1-alkynes. Selected catalysts were immobilized within the mesopores of SBA-15. The confinement effects either provided by the ligands or the mesoporous support have been studied and allow for hydrosilylation with β(Z)-selectivity of up to 100 % with both Rh(I) and Rh(III) complexes.</p> <p>All primary data files of measurements and processed data of the journal article mentioned under related publications from Buchmeiser group can be found here.</p> The following dataset contains the following data types: NMR Spectra and HRMS data. The Crystal data (see related datasets) is deposited in the Cambridge Structural Database (CSD) of the Cambridge Crystallographic Data Centre (CCDC).
