Abstract

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. All primary data files of measurements and processed data of the journal article mentioned under related publications from Buchmeiser group can be found here. 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).
