bicyclic olefins. Under reductive conditions (HCOOH, Et 3 N), the complexes generated in situ from imidazolinium salts and Pd(OAc) 2 catalyzed the hydroarylation of bicyclic alkenes with aryl iodides, providing the hydroarylation products with high turnover numbers (TON, up to 1.9·10 5 ) and turnover frequencies (TOF, up to 6.3·10 4 ).
新型三芳基膦官能化咪唑啉盐已被制备并成功应用于钯催化的双环烯烃加氢芳基化。在还原条件 (HCOOH, Et 3 N) 下,咪唑啉盐和 Pd(OAc) 2 原位生成的配合物催化双环烯烃与芳基碘的加氢芳基化,提供具有高周转数(TON,高达 1.9· 10 5 ) 和周转频率(TOF,高达6.3·10 4 )。
