Abstract

Steric interaction between terminal allyl substituent and the proximal 3-methyl group of the pyrazole can result in a severe distortion of the π-allyl orientation, as diagnosed by the downfield chemical shift of the central proton of the allyl group and confirmed by the X-ray crystal structure of a π-cinnamyl complex of molybdenum containing hydrotris-(3,5-dimethylpyrazolyl)borate ligand.
