Counterions in control: The rhodium(I)‐catalyzed coupling of one molecule of aldehyde and two molecules of allene gave β,γ‐dialkylidene ketones (see scheme). Either of two constitutional isomers was selectively obtained depending on the counterion of the rhodium(I) complex.
控制中的抗衡离子:铑(I)催化的一个分子醛和两个分子的丙二烯偶联生成β,γ-二亚烷基酮(参见方案)。根据铑(I)配合物的抗衡离子选择性地获得两种结构异构体。
