It has been established that reductive complexation of functionalized benzofulvenes, which are readily prepared from commercially available indene and 2‐methylindene, with RhCl3 in ethanol affords the corresponding indenyl–rhodium(III) dichlorides bearing substituents at the 1‐ (H or CO2Et), 2‐ (H or Me), and 3‐ [CH2Ph or CH2(2‐MeOC6H4)] positions. The indenyl–rhodium(III) complexes bearing one ethoxycarbonyl group showed higher thermal stability and regioselectivity than our previously reported CpERhIII complex toward the oxidative [3+2] annulation of acetanilides with internal alkynes.

功能化(η5-茚基)铑(III)配合物的合成及其在CH键功能化中的应用

已经确定,可以很容易地从商业上可获得的茚和2-甲基茚与官能团苯并富勒烯与乙醇中的RhCl 3进行还原络合,得到相应的茚-铑(III)二氯化物,它们在1-(H或CO 2)处带有取代基。Et),2-(H或Me)和3- [CH 2 Ph或CH 2(2-MeOC 6 H 4)]位置。带有一个乙氧基羰基的茚-铑(III)配合物比我们先前报道的Cp E Rh III配合物对乙炔化物与内部炔烃的氧化[3 + 2]环合反应显示出更高的热稳定性和区域选择性。
