A highlyregioselective and stereospecific rhodium-catalyzed cyanomethylation of tertiary allyliccarbonates for the construction of acyclic β-quaternary stereogenic nitriles is described. This protocol represents the first example of a metal-catalyzed allylicsubstitution reaction using a triorganosilyl-stabilized acetonitrile anion, which permits access to several carbonyl derivatives that are challenging
