%X Spiropyridines, a novel series of C2-symmetric ligands, can be obtained in moderate yields by means of Co(I)-catalyzed double cocyclization
between bis-alkynenitriles and alkynes. This one-step method allowed the first synthesis of the interesting 7,7‘- and 8,8‘-spyropyridines from
acyclic precursors.
