The first approach is based on the palladium-catalyzed cross-coupling reaction of halogenated azines with organozinc derivatives of ferrocenes (the Negishi reaction). The second approach exploits a new synthetic methodology, which provides a shorter pathway, through the direct C–H functionalization of aromatics by the C–C coupling of halogen-free (hetero)arenes with lithium ferrocenes bearing stereogenic C and S atoms. The palladium complexes of P,N-ligands have been used as catalysts for the Tsuji–Trost reaction, which proceeds with high enantioselectivity to give allylic substitution products in good yields. \\\\expert2\\nbo\\Journal of Organic Chemistry\\2014, v.79, p.8659.pdf |
