Conformational Equilibria and Stereospecific Synthesis
Pi allyl-complexes have been used as reactants or have been postulated as intermediates in many of the reactions discussed at this symposium. Our studies of rearrangement mechanisms and conformational equilibria often provide a rationale for the product distributions and stereochemistry in these reactions. It appears that steric factors tend to control stereochemistry. Kinetic and thermodynamic parameters of some palladium complexes will be reviewed in the perspective of their implications in rearrangements, stereospecific reactions, and racemization processes.
