All primary data files and processed data of the journal article from Buchmeiser group, in which cationic tungsten oxo NHC complexes are synthesized via hydrolysis of cationic alkylidyne NHC complexes. NMR data of all pure compounds and NMR experiments. Gc-MS data of Metathesis reactions and crystal data for all crystal structures.

NMR data is subdivided in Nmr Experiments which are included in the folder NMR tests. The NMR data for the pure compounds can be found in the folder pure compounds. Productivites for Metathesis reactions were measured via GC-MS. GC-MS data is divided in catalyst substrate ratio 1:10000 and 1:2000 and then subdivided in "Stammlösung" and the catalyst descriptions.
