Manganese catalysed dehydrogenative synthesis of polyureas from diformamide and diamines.

We report here the synthesis of polyureas from the dehydrogenative coupling of diamines and diformamides. The reaction is catalysed by a manganese pincer complex and releases H gas as the only by-product making the process atom-economic and sustainable. The reported method is greener in comparison to the current state-of-the-art production routes that involve diisocyanate and phosgene feedstock.

Enhanced Photoluminescence and Reduced Dimensionality via Vacancy Ordering in a 10H Halide Perovskite.

Vacancy-ordered halide perovskites have received great interest in optoelectronic applications. In this work, we report the novel inorganic halide CsMnSbCl with a distinctive 10H (10-layer hexagonal) perovskite polytype structure with (hcccc) stacking. CsMnSbCl has 30% B-site vacancies ordered at both corner- and face-sharing sites, resulting in [MnSbCl] columns, i.

Direct synthesis of polyureas from the dehydrogenative coupling of diamines and methanol.

We report here the first example of the direct synthesis of polyureas from the dehydrogenative coupling of diamines and methanol using a ruthenium pincer catalyst. The present methodology replaces the use of toxic diisocyanates, conventionally used for the production of polyureas, with methanol, which is renewable, less toxic, and cheaper, making the overall process safer and more sustainable. Further advantages of the current method have been demonstrated by the synthesis of a renewable, a chiral, and the first 13C-labelled polyurea.
