[EN] MANGANESE BASED COMPLEXES AND USES THEREOF FOR HOMOGENEOUS CATALYSIS [FR] COMPLEXES À BASE DE MANGANÈSE ET LEURS UTILISATIONS SERVANT À UNE CATALYSE HOMOGÈNE
base-metal-catalyzed dehydrogenative coupling of diols and amines to form cyclic imides is reported. The reaction is catalyzed by a pincercomplex of the earth abundant manganese and forms hydrogen gas as the sole byproduct, making the overall process atom economical and environmentallybenign.
