This cover feature shows the great potential of the ferrocene molecule for a custom-made synthesis of ferrocene ligands, especially asymmetric disubstituted species bearing phosphine ligands and their corresponding group 11 metal complexes. These derivatives may be suitable for application in catalysis. Details are discussed in the article by M. D. Villacampa, M. C. Gimeno et al. on page 247 ff (DOI:
10.1002/ejic.201600929). For more on the story behind the cover research, see the Cover Profile (DOI:
