Stabilization of Silicon-Carbon Mixed Oxides.

The first carbene-stabilized silicon-carbon mixed oxide, (SiO2)2CO2 (4), was synthesized by CO2 oxidation of either carbene-stabilized disilicon, L:Si═Si:L (L: = :C{N(2,6-Pr(i)2C6H3)CH}2) (1), or carbene-stabilized Si2O3 (2) (which can be obtained via N2O oxidation of 1). The structure and bonding of 4 was probed by both experimental and computational methods.
