The synthesis of neutral tungsten sulfido alkylidene complexes as well as cationic tungsten alkylidene NHC complexes is outlined. The first tungsten sulfido alkylidene complexes for olefin metathesis reactions were synthesized. Alkylidyne complexes were used as precursors and were reacted with hydrogen sulfide to protonate the alkylidyne ligand.

Data from collaborating groups can be found in a separate data set.

The data is structured according to figures and schemes in the research article and contains the following data types: NMR Spectra and integrals of GC-MS measurements. GC-MS data was evaluated with MassHunter software by agilent. NMR data was evaluated with MestreNova.

Crystal data (see related datasets) is deposited in the Cambridge Structural Database (CSD) of the Cambridge Crystallographic Data Centre (CCDC).

Data is structured in NMR measurements (Spectra of new compounds and NMR experiments (W02+BCF)). And GC-MS measurements of the metathesis reactions. (Further information can be found in the readme file)
