New ligand for old reaction: The title reaction of aryltriflates with aliphatic olefins leads to substitution at the internal position with high selectivity. The ratio of the desired isomer (shown in the scheme) to the sum of all other isomers is generally above 10:1. The key to success is the use of a ferrocene bisphosphine ligand (R= 1‐naphthyl). The reaction can be easily scaled up, and minor isomers
旧反应的新配体:芳基三氟甲磺酸与脂族烯烃的标题反应可在内部位置以高选择性进行取代。所需异构体(在方案中显示)与所有其他异构体之和的比例通常高于10:1。成功的关键是使用二茂铁双膦配体(R = 1-萘基)。该反应可以容易地按比例放大,并且可以通过色谱法分离较小的异构体。
