The first example of phosphine-free, NHC–Pd(II) complex catalyzed direct C–H bond benzylation of (benzo)oxazoles with benzyl chlorides was reported in this paper. Under the suitable conditions, all reactions worked well enough to give the desired C2-benzylated products in good to almost quantitative yields, providing a facile and straight pathway for the C–H bond benzylation of (benzo)oxazoles within short time.

N-杂环卡宾-Pd（II）-1-甲基咪唑配合物催化苄基氯与苯并恶唑的CH键苄基化

本文报道了第一个不含膦的NHC-Pd（II）络合物催化（苯并）恶唑直接与苄基氯形成CH键的苄基化反应。在合适的条件下，所有反应均能很好地完成，以令人满意的或几乎定量的产率获得所需的C2-苄基化产物，为（苯并）恶唑的C–H键苄基化提供了便捷的途径。
