The synthesis, characterization, and structure‐guided application of a new class of highly versatile chiral C 2 ‐symmetric diamine‐oligothiophene ligands in Pd‐catalyzed asymmetric transformations are presented. Experimental investigations of the intimate role of pendant π‐conjugate oligothiophenes in determining the catalytic activity of the corresponding chiral Pd complexes are described. Their unusual behavior opens up new routes toward the logical design of finely tuned organometallic catalysts by remote structural functionalizations.
