Abstract
AbstractThe donor‐stabilized sila‐β‐lactone 1 reacts with CO2 via a remarkable reversible [2+2]‐cycloaddition reaction to form the spiro‐cyclic silicon carbonate derivative 2. Furthermore, photolysis of 2 under pressure of CO2 affords the first persistent SiO2–CO2 cycloadduct 3, presenting a Si2O4‐like structure, which is stabilized by a Lewis donor–acceptor type ligand. As predicted by theoretical calculations, in marked contrast to the thermodynamically stable SiO2 dimer, the SiO2–CO2 mixed cycloadduct 3 is labile and readily releases CO2.
