以2-(磺酰亚氨基)吡咯烷为原料，通过乙酸镝的配体取代反应，合成了一类新的以(3，1)几何异构体为主的四胺酸铋盐。其中，(3，1)-Rh2(MSIP)4具有较好的催化活性。在(3，1)-Rh2(MSIP)4存在下，各种苄基衍生物，包括强缺电子的芳烃，如1-乙基-4-硝基苯，在水中很容易被廉价的氧化剂T-Hydro(R)(70wt.-%叔丁基氢过氧化氢)氧化。
A new class of dirhodium(II) tetraamidinates derived from 2-(sulfonylimino)pyrrolidines has been prepared through ligand substitution by using dirhodium(II) acetate, in which (3,1) geometric isomers are formed predominantly. Among these complexes, (3,1)-Rh2(Msip)4, exhibits good catalytic performance in benzylic oxidation. In the presence of (3,1)-Rh2(Msip)4 a variety of benzylic derivatives, including strongly electron-deficient arylalkanes such as 1-ethyl-4-nitrobenzene, are readily oxidized in water by the inexpensive oxidant T-HYDRO (R) (70 wt.-% aqueous tert-butyl hydroperoxide).
