LUMO umpolung in reactions of n-systems with nucleophiles It is possible to invert stereoelectronic requirements for nucleophilic processes and render them similar to the stereoelectronics of electrophilic reactions. Such polarity inversion ( the umpolung ) can be accomplished via coordination of a x-bond to an... [Pg.28]
