Abstract

Iminophosphonamido-supported silylaminostannylenes activate CO₂ to afford siloxystannylene and isocyanates via carbamatostannylene intermediates. DFT calculations support a two-step rearrangement involving nucleophilic attack and silyl migration, offering a rare example of a main-group CO₂ valorisation through isocyanate formation.

亚氨基膦胺基乙烯能定量地将CO₂转化为异氰酸酯

亚磷酰胺负载的硅氨基丁烯通过氨基丁烯中间体活化CO₂生成硅氧硅氧烷和异氰酸酯。DFT计算支持涉及亲核攻击和硅基迁移的两步重排，提供了一个罕见的通过异氰酸酯形成主基CO₂增值的例子。
