The complexes [M(CO)5(RSCH2SR)] (M Cr, R Et, iPr, tBu; M W, R Me, Et, iPr, tBu) were synthesised. Total bandshape NMR analysis was used to measure energies of inversion of the coordinated S atom in the tungsten complexes. ΔG‡ (298.15 K) values were in the range 34–42 kJ mol−1. An X-ray structure of [W(CO)5(tBuSCH2StBu)] was obtained.
配合物[M(CO)5(RSCH 2 SR)](M铬,R的Et,我PR,吨卜; MW,RME等,我PR,吨卜)的合成。总带状NMR分析用于测量钨配合物中配位的S原子的转化能量。Δ ģ ‡(298.15 K)值在范围34-42千焦耳摩尔-1。获得了[W(CO)5(t BuSCH 2 S t Bu)]的X射线结构。
