from the decomposition of diazo compounds, are valued for their capacity to perform a variety of transformations. A unique class of acyclic, bis-diazo compounds, the donor-acceptor-acceptor 1,3-bisdiazo compounds, are described herein. These compounds are available from acyclic β-keto esters and especially reactive at the donor-acceptor diazo unit. These bisdiazo compounds react smoothly with rhodium acetate
重氮化合物分解产生的金属卡宾因其执行各种转化的能力而受到重视。本文描述了一类独特的无环双重氮化合物,供体-受体-受体1,3-双重氮化合物。这些化合物可得自无环β-酮酯,尤其是在给体-受体重氮单元上具有反应性。这些双重氮化合物可与乙酸铑和醇平稳反应,生成单重氮环状原酸酯,大概是通过捕获瞬态氧鎓叶立德。
