Here, we describe the isolation and full characterization of the first tetraamido tin(II) dianion, its behavior as ligand towards transition metals, and its reactivity as a tin-centered nucleophile. Experimental values such as the Tolman electronic parameter (TEP) and computations attest tin-located σ-donor ability exceeding that of carbenes or electron-rich phosphines. Against transition metals, the stannate(II) can act as η1- or η5-type ligand. With aldehydes, it reacts by hydride substitution to give valuable acyl stannates. The reductive dehalogenation of iodobenzene indicates facile redox pathways mediated by halogen bond interaction. Calix[4]pyrrolato stannate(II) represents the first example of this macrocyclic ligand in low-valent p-block element chemistry.","8 S.","https://refubium.fu-berlin.de/handle/fub188/34182||http://dx.doi.org/10.17169/refubium-33900","eng","https://creativecommons.org/licenses/by-nc/4.0/","500 Naturwissenschaften und Mathematik::540 Chemie::540 Chemie und zugeordnete Wissenschaften","Calix[4]Pyrrole||Dianions||Low-Valent||Tin||σ-Donor","Calix[4]pyrrolato Stannate(II): A Tetraamido Tin(II) Dianion and Strong Metal-Centered σ-Donor","Wissenschaftlicher Artikel","open access","e202116615","10.1002/anie.202116615","Angewandte Chemie International Edition","13","https://doi.org/10.1002/anie.202116615","61","1521-3773","Biologie, Chemie, Pharmazie","Institut für Chemie und Biochemie:::bdaf1c47-f341-464f-b012-0d24067d34b8:::600","DEAL Wiley","Die Publikation wurde aus Open Access Publikationsgeldern der Freien Universität Berlin gefördert.","no","WoS-Alert"
