A soft alternative to the dominant {(C5Me5)2U} motif.
Pincers do something for U that sandwiches don't: The dead-ends in the metallocene chemistry of the actinides can be circumvented by using a soft PNP pincer ligand (see scheme). The PNP ligand has been shown to be flexible, hemilabile, and capable of stabilizing low- and high-valent uranium species. The bis(PNP) framework is a valuable alternative to the (C(5)Me(5))(2) ligand set, offering distinct structures and reaction patterns.
