The construction of carbon–carbon bonds and the control of product stereochemistry are two of the most important challenges in organic synthesis. The substitution reaction of an alkyl electrophile by an alkyl nucleophile is a potentially powerful, convergent strategy for organic synthesis; however, in practice, classical mechanisms for substitution reactions (SN1 and SN2 pathways) are limited in their ability to generate carbon–carbon bonds and to control product stereochemistry when beginning with readily available racemic starting materials. We have developed a chiral nickel catalyst that couples, for the first time, racemic electrophiles with racemic nucleophiles to form carbon–carbon bonds in doubly stereoconvergent processes (i.e., affording a single stereoisomer of the product from two stereochemical mixtures of starting materials). The nickel-catalyzed coupling of two racemic partners to form a new carbon–carbon bond as a single stereoisomer is described.
