In this dataset HPLC (high performance liquid chromatography) chromatograms of the products of the rhodium-catalyzed 1,2-addition and NMR spectra of all prepared catalysts and catalysis products (NMR) are included. The described 1,2-addition product is an N-tosyl amide which was formed from the reaction of triphenylboroxine with an N-tosyl imine. The catalysts are the chiral Rh norbornadiene phosphine complexes [RhCl(L1)(P(Ad)2(n-Bu))] and [RhCl(L1)(PPh3)]. Furthermore, the NMR data of phosphine complexation experiments is deposited. This data was collected to screen for suitable phosphines for the later quantification of accessible Rh diene complexes on SBA-15 via solid state NMR. Crystallographic data was published in Cambridge Structural Database (CSD) of the Cambridge Crystallographic Data Centre (CCDC) as stated under related datasets. In this dataset additional data from the crystal structure of [RhCl(L1)(P(Ad)2(n-Bu))] is included (plotted structure, CIF file, PDB file, RES file and a DAT file with tables listing all the significant measuring parameters, bond angles, bond distances and atom coordinates).
