Abstract
Steric interaction between a terminal allyl substituent and the proxim al 3-methyl group of the pyrazole can result in a severe distortion of the pi-allyl orientation, as diagnosed by the downfield chemical shif t of the central proton of the allyl group and confirmed by the X-ray crystal structure of a pi-cinnamyl complex of molybdenum containing hy drotris-(3,5-dimethylpyrazolyl)borate ligand.
