Syntheses and X-ray crystal structures of monomeric zinc and mercury bis(silylamides)

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

“…Overall, the Sr 6 framework chemically fixates twelve molar equivalents of CO 2 , half by the formation of two [N(CO 2 ) 3 ] 3À ligands and the other half by CO 2 insertion to form the unprecedented phosphanyl-substituted carbamate O 2 CN(PPh 2 ) 2 .…”

“…[1] More specifically, we [2] and others [3] have previously studied the reaction chemistry of CO 2 with main-group metal amides to yield organic isocyanates and carbodiimides as products. Previous reactions of these main-group complexes with CO 2 have utilized silylcontaining amido groups as ligands.…”

“…Remarkably, two N(PPh 2 ) 2 ligands have reacted with CO 2 to cleave the PPh 2 groups from nitrogen and formally insert three molar equivalents of CO 2 3 molecule. [14] While the parent triprotic acid complex is unknown, organic esters of the formula N(CO 2 R) 3 (where R = Et, tBu, or substituted cyclohexyl derivatives) have been prepared by conventional synthetic routes that do not involve direct insertions of CO 2 .…”

Dispersion Makes a Difference – The Solid‐State Structure of Hg[N(SiMe3)2]2

“…: 11 °C), it is difficult to prepare samples for single‐crystal X‐ray diffraction. Generally, to the best of our knowledge, the only known solid‐state structures of mercury(II) bis(disilyl)amides are those of Hg[N(SiMe 3 )N(SiPh 2 t Bu)] 2 and Hg[N{Si(Me 2 )CH 2 CH 2 Si(Me 2 )}] 2 , which is why we want to report and explain the solid‐state structure as well as the solid state Raman spectrum of 1 in comparison to its gas phase structure.…”

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

“…With interests extending from the economic desire to convert a "useless" C 1 source into higher-valued products to the desire to mitigate global warming, CO 2 fixation studies span an enormous range. [1] More specifically, we [2] and others [3] have previously studied the reaction chemistry of CO 2 with main-group metal amides to yield organic isocyanates and carbodiimides as products. Previous reactions of these main-group complexes with CO 2 have utilized silylcontaining amido groups as ligands.…”
