Rh-complex catalysed directed hydrogenation of (α-hydroxyalkyl)vinyl sulfones follows the same stereochemical course as the corresponding acrylates, via HO-coordination; hydrogenation of the related (α-hydroxyalkyl)vinyl sulfoxides is directed by S–O coordination, which overrides HO-participation and is shown to be general.
Rh 络合物催化的(α-羟烷基)乙烯基砜的直接氢化反应遵循与相应丙烯酸酯相同的立体化学过程,通过 HO 配位;相关的(α-羟烷基)乙烯基亚砜的氢化是由S-O配位指导的,它优先于HO-参与,并且被证明是普遍的。
