Introduction of electron- withdrawing and electron-donating groups at the O-chelated alkylidene ligand allowed for the tuning of both the onset temperature of polymerization (Tonset) and the temperature of the exotherm maximum (Texo,max). In addition, N-chelated complexes were synthesized using easily available 2-vinylpyridine or 2-vinyl- N,N-dimethylaniline to yield five-membered and, for the first time, four-membered molybdenum imido alkylidene NHC chelates. With these precatalysts, Tonset and Texo,max could be varied between 52 and 142 °C and between 99 and 174 °C, respectively. All primary data files and processed data of the journal article from the Buchmeiser group. Tuning the Latent Behavior of Molybdenum Imido Alkylidene N-Heterocyclic Carbene Complexes in Dicyclopentadiene Polymerization. Nuclear magnetic resonance (NMR) spectra are uploaded. Also differential scanning calorimetry (DSC) data are available.
