fluxional nature of complexes 3 in solution resulting from the Ru2S2 ring inversion. Complex 3a (R iPr) underwent oxidative addition of RX (R PhCH2CH2 or PhCH2, X Br; R Me or Et, X I) and H2 across the Ru2 center to give [Cp★RuR(μ-SiPr)2RuCp★X] (7) and [Cp★RuH(μ-SiPr)2RuCp★H], respectively. The structure of 7a (R PhCH2CH2, X Br) has been determined by X-ray crystallography. Crystal data for 3c:
的[Cp★的RuCl]的反应4(CP★η 5 -C 5我5)与纳斯尔(R我PR,吨卜,2,6--ME 2 ç 6 ħ 3)在THF双核,得到钌II络合物与两个桥接硫醇盐配体[Cp★Ru(μ-SR)2 RuCp★](3)。X射线分析3c(R = 2,6-Me 2 C 6 H 3)揭示了具有两个赤道C 6 H 3 Me 2的折叠Ru 2 S 2芯结构。固态有-2,6个基团,而1 H NMR可变温度研究的结果可诊断因Ru 2 S 2环反转而形成的络合物3在溶液中的通量性质。复杂的图3a(R我PR)后行氧化加成RX的(R的PhCH 2 CH 2或物理信道2,X溴; RMe或Et,XI)和H 2穿过的Ru 2中心,得到的[Cp ★RUR(μ-S我PR)2 RuCp★X](7)和的[Cp★期RuH(μ-S我PR)2 RuCp★H],分别。的结构图7a(R的PhCH 2 CH 2,X溴
