| Abstract: | An electronically neutral 2‐arylsilacyclobutane generates a nucleophilic carbanion at room temperature through cleavage of the benzylic C?Si bond when simply dissolved in polar aprotic solvents such as N,N‐dimethylformamide (DMF). The nucleophilic species is capable of capturing carbon dioxide to furnish a silalactone. The carboxylation reaction is unique in that no additional activating agents are required. |
