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
使用乙酸二铑(II)通过配体取代制备了一类新的衍生自 2-(磺酰基亚氨基)吡咯烷的四脒二铑 (II),其中主要形成 (3,1) 几何异构体。在这些配合物中,(3,1)-Rh2(Msip)4 在苄基氧化中表现出良好的催化性能。在 (3,1)-Rh2(Msip)4 存在下,多种苄基衍生物,包括强缺电子的芳基烷烃,如 1-乙基-4-硝基苯,在水中很容易被廉价的氧化剂 T-HYDRO 氧化。 R) (70 wt.-% 叔丁基氢过氧化物水溶液)。
