摘要：

(Figure Presented) Under mild conditions CO2 reacts with [Sr{N(PPh2)2}2](THF)3 to oxidatively cleave PPh2 groups, resulting in the new ligand [N(CO 2)3]3- in [Sr6{O2CN- (PPh2)2}6{N(CO2)3} 2] (see core structure; Sr green, O red, N blue, C black). The Sr6 framework chemically fixates twelve equivalents of CO 2, half by the formation of two [N(CO2)3] 3- ligands and the other half by CO2 insertion to form the unprecedented phosphanyl-substituted carbamate ligand O2CN(PPh 2)2. © 2008 Wiley-VCH Verlag GmbH & Co.
