Facile syntheses of dissymmetric ferrocene-functionalized Lewis acids and acid–base pairs

Abstract

A facile synthetic approach is reported for the synthesis of dissymmetric 1,2-ferrocenediyl Lewis acids and mixed acid-base pairs including the first example of a 1-phosphino-2-borylferrocene; the use of non-racemic electrophiles allows for the isolation of single diastereomer products.
