摘要

Abstract: A systematic study of the relationship between ligand structure and saturation rate constants (k,) in the amine-catalyzed osmylation of terminal olefins was carried out with the aim of learning more about the interactions between the reactants (Le. 0~ 04, the ligand, and the olefin) and of establishing the origin of the large rate accelerations observed with cinchona alkaloid ligands. The results reveal that the saturation rate constants are ...
