An Rh(I)-catalyzed cross-coupling of diazoesters with arylsiloxanes has been successfully achieved. This transformation is a new method for the construction of the C(sp(3))-C(sp(2)) bond, thus providing an alternative synthesis of α-aryl esters. Rh(I)-carbene migratory insertion has been proposed to be involved in this coupling reaction. The reaction represents the first example of utilizing arylsiloxane as the coupling partner in the carbene-involved cross-coupling reactions.
铑(I)催化的重氮酯与芳基硅烷的交叉偶联已成功实现。这种转化是构建 C(sp(3))-C(sp(2))键的新方法,为α-芳基酯的合成提供了一种替代方法。铑(I)-卡宾迁移插入被认为参与了这种偶联反应。该反应代表了首例利用芳基硅烷作为卡宾参与的交叉偶联反应中的偶联伙伴的例子。
