important building blocks. Herein, we presented an efficient catalytic system for the α-arylation of aryl ketones with inactive aryl chlorides by firstly using N,N′-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr)-ligated chiral oxazoline palladacycles, and tolerated a wide range of substrates at low catalyst loadings, leading to the desired products in good to excellent yields.
羰基化合物的 α-芳基衍生物是重要的组成部分。在此,我们首先使用N , N ′-双(2,6-二异丙基苯基)-咪唑-2-亚基 (IPr)-连接的手性恶唑啉钯环,提出了一种高效的芳基酮与非活性芳基氯的 α-芳基化催化体系, 并在低催化剂负载下耐受多种底物, 从而以良好的收率获得所需的产品。
