NMR chemical shift analysis decodes olefin oligo- and polymerization activity of d0 group 4 metal complexes [Chemistry]

d0 metal-alkyl complexes (M = Ti, Zr, and Hf) show specific activity and selectivity in olefin polymerization and oligomerization depending on their ligand set and charge. Here, we show by a combined experimental and computational study that the 13C NMR chemical shift tensors of the α-carbon of metal alkyls that...
