terminal alkynes has been described. The reaction is oxidant/base-free and tolerates a wide variety of functional groups and has been successfully extended with 1,3 and 1,4-bis(phenylethynyl)benzenes to afford 1,3- and 1,4-bis(4-methylquinolin-2-yl)benzenes and 2-(3/4-ethynylphenyl)-4-methylquinolines. Furthermore, the control experiment supports the proposed reaction mechanism.
已经描述了使用2-氨基hydr和末端炔烃的铑催化的,化学和区域选择性的功能化喹啉的合成。该反应不含氧化剂/碱,可耐受多种官能团,并已成功地与1,3和1,4-双(苯基乙炔基)苯反应,得到1,3-和1,4-双(4-)甲基喹啉-2-基)苯和2-(3 / 4-乙炔基苯基)-4-甲基喹啉。此外,对照实验支持所提出的反应机理。
