Nitrodiazo compounds cyclopropanate electron rich alkenes in the presence of rhodium(II) acetate. The yields and diastereoselectivities are dependent on both the alkene and the nitrodiazo precursor. Nitrocyclopropanecarboxylates undergo ring opening, reduction and hydrolysis.
硝基重氮化合物在乙酸铑(II)的存在下形成环丙酸酯富电子的烯烃。产率和非对映选择性同时取决于烯烃和硝基二偶氮前体。硝基环丙烷羧酸酯经历开环,还原和水解作用。
