Pyridines featuring two or more halogen atoms react with silylformamidine via insertion into the most acidic C−H bond either at the γ or β-positions affording the corresponding aminals. Their hydrolysis gave aldehydes. The reaction proceeds via H-abstraction from pyridines by the strong base-carbenic form of silylformamidine followed by formation of C−C bond between the formamidinium cation and the
具有两个或多个卤素原子的吡啶通过在 γ 或 β 位插入酸性最强的 C-H 键与甲硅烷基甲脒反应,得到相应的缩醛胺。它们水解产生醛。该反应通过甲硅烷基甲脒的强碱碳形式从吡啶中夺氢,然后在甲脒阳离子和吡啶阴离子之间形成CC键。
