Nucleophilic Substitutions Involving Ferrates

A variety of different allylic carbonates and pronucleophiles can be employed under the standard reaction conditions, giving rise to the allylated products in good to excellent yields and regioselectivities. Moreover, the reaction scope was extended to

I ntroduction Substitutions involving ferrates as the catalytically active species might also encounter regio- and stereoselectivity problems (Scheme 7.15). The nucleophilic substitution of the leaving group can occur either in an SN2- [Equation (7.8),...
