The preparations of [RSRh(CO)2]2 (R = CH3, C6H5, p-FC6H4, C6F5) are reported, and their stereochemistry investigated. Rapid cleavage of the thio bridge by triphenylphosphine leads to complexes of the type cis-RSRh(CO) (PPh3)2. The slow isomerisation of these to the trans-isomer can be followed spectrometrically.
报道了[RSRh(CO)2 ] 2(R = CH 3,C 6 H 5,p -FC 6 H 4,C 6 F 5)的制备方法,并对其立体

三苯基膦快速裂解
硫桥导致了顺式-RSRh(CO)(PPh 3)2型复合物。这些可以缓慢地异构化为反式异构体,可以用光谱法进行。
