All primary data files related to the publication. Procedures, recation conditions and used analytical equipment is discussed in detail in the experimental section or the supporting information of the paper. Productivities in olefin metathesis reactions were examined via gas-chromatography / mass spectrometry (GC-MS) analysis and can be found in the GC-MS folder. Furthermore, the GC-MS folder contains an Excel-file in which the names of the data files are listed and assigned to table entries in the publication. Novel complexes were examined via nuclear magnetic resonance (NMR) spectroscopy and the spectra can be found in NMR folder. The NMR folder also contains NMR experiments mentioned in the paper and shown in the Supplementary Information. NMR Spectra are named according to the numbering in the publication. All crystal data mentioned in the paper can be found in the related datasets. Size exclusion chromatography (SEC) data are provided as text-files and can be plotted with software such as MS Excel.

NMR spectra were processed with MestreNova. GC-MS data was processed with Agilent MassHunter.
