those found for the crystalstructures containing the fragments [Ln(III)(phen)] and [Ln(III)(bipy)] obtained from the Cambridge Structural Database. The influence exerted by the electron-attracting groups on the coordination ability of the ligands, that in some cases becomes lack of coordination of the lanthanide ions, has been also detected in solution where the loss of the ligand has been followed

A direct method for C–H dicarbamoylations of phenanthrolines has been developed, which is capable of directly installing primary, secondary as well as tertiary amides. This is a significant improvement on the previous direct method, which was limited to primary amides. The metal-, light-, and catalyst-free Minisci-type reaction is cheap, operationally simple, and scalable. We demonstrate that the step
