All primary data files and processed data of the journal article from Buchmeiser group. Productivities in alkyne metathesis reactions (Paper, Table 1) was examined via gas-chromatography / mass spectrometry analysis and can be found in the GC-MS data folder. Novel complexes were examined via NMR spectroscopy and the spectra can be found in NMR data -> pure compounds. The NMR folder also contains NMR experiments mentioned in the paper and shown in the Supplementary Information. All crystal data mentioned in the paper can be found in the related datasets.

W1 - W20 are the complexes described in the paper. Details about the methods used are mentioned in the experimental section in the paper. NMR spectra were processed with MestreNova. GC-MS data was processed with Agilent MassHunter. Catalysts in GC-MS were grouped in this way, because the same stock solutions were used with these catalysts (e.g. PH212-216), which is why the blank sample is the same.
