Insertion of Carbon Dioxide into Main‐Group Complexes: Formation of the [N(CO2)3]3− Ligand

Abstract: Unter milden Bedingungen reagiert CO2 mit [Sr{N(PPh2)2}2](THF)3 unter oxidativer Abspaltung der PPh2‐Gruppen und der Bildung des Liganden [N(CO2)3]3− zu [Sr6{O2CN(PPh2)2}6{N(CO2)3}2] (siehe Struktur des Molekülkerns; Sr grün, O rot, N blau, C schwarz). Das Sr6‐Gerüst fixiert zwölf Äquivalente CO2, sechs davon durch die Bildung zweier [N(CO2)3]3−‐Liganden und die anderen sechs durch CO2‐Insertion unter Bildung des Phosphanyl‐substituierten Carbamatliganden O2CN(PPh2)2.

“…[121] There are a number of reactions of main-group-element reagents with CO 2 , such as the trapping reaction with amines [122] or main-group-metal amides, [123] or the conversion of CO 2 into bicarbonate induced by organic bases in the presence of hydroxide. [124] Some chelate complexes of zinc catalyze the addition of CO 2 to epoxides.…”

“…The reaction of an alkylamido group with CO2, leading to the generation of a carbamato ligand, has found widespread use for s-block [42] and early d-transition metals [125,126,[128][129][130]179]. In this regard, new fascinating examples have been recently reported [133,[180][181][182][183][184][185][186]. The simplest cases are represented by homoleptic metal amido complexes undergoing selective carbonation, leading to mixed amido-carbamato derivatives.…”

“…[121] Es gibt eine Reihe von Reaktionen von Hauptgruppenelementverbindungen mit CO 2 , z. B. die Abfangreaktion mit Aminen [122] oder Metallamiden [123] oder die Umwandlung von CO 2 in Bicarbonat, induziert durch organische Basen in Gegenwart von Hydroxid. [124] Einige Chelatligandkomplexe des Zinks katalysieren die Addition von CO 2 an Epoxide.…”
