过渡金属催化环加成反应是合成单环及多环化合物的重要方法,也是有机化学的研究热点之一.综述了近年来铱催化环加成反应的研究进展,主要包括了[2+2+1],[2+2+2],[4+2],1,3-偶极环加成反应等,及少量关于[3+2+2],[3+2],[5+1]环加成反应的报道,并讨论了部分铱催化环加成反应机理.
The transition metal-catalyzed cycloaddition reaction is an important method for the synthesis of monocyclic and polycyclic compounds and is also one of the hot topics in organic chemistry.In this paper, the progress in the research on the cycloaddition reaction of iridium in recent years is summarized, including [2 + 2 + 1], [2 + 2 + 2], [4 + 2], 1,3-dipolar cycloaddition reaction, and a small amount of information about [3 + 2 + 2], [3 + 2], [5 + 1 ] Cycloaddition reactions reported, and some iridium catalytic cycloaddition reaction mechanism was discussed.
