反离子控制:铑(I)催化一个醛分子和两个烯分子偶联得到β, γ-二烷基二烯酮(见方案)。根据铑(I)配合物的反离子选择性地得到两种构象异构体中的任何一种。
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.
