with H2S to yield H2 and the bridged-sulfido complexes Pd2X2(μ-S)(dmpm)2 (2a–c), of which 2a and 2b are structurally characterized. With 1a, two rapid reversible equilibria are observed by NMR spectroscopy below −30 °C, and two reaction intermediates are detected; both are likely hydrido(mercapto) species. Reaction of 1a with 1 equiv of elemental sulfur also yields 2a. The reaction of 1a with COS results

SF6 and SF5 organyls by SF and SC bond‐activation reactions at [Rh(μ‐H)(dippp)}2] under mild conditions is reported. Fluorido and thiolato species were identified as products or intermediates, and were characterized by X‐ray diffraction analysis and multinuclear NMR spectroscopy. An unprecedented cyclic process for the conversion of the potent greenhouse gas SF6 into H2S was developed.

The matrix isolation technique has been used to study the initial intermediate products of the reaction of molecular fluorine, F 2 , with several alkyl sulfides, as well as with trimethylphosphine. While previous studies of the reaction of these bases with ClF and Cl 2 demonstrated that charge transfer complexes are formed no evidence has been here for complex formation. Rather direct reaction occurs
摘要 基质分离技术已用于研究分子氟 F 2 与几种烷基硫化物以及三甲基膦反应的初始中间产物。虽然之前对这些碱与 ClF 和 Cl 2 反应的研究表明形成了电荷转移复合物,但这里没有证据表明复合物形成。所研究的每个系统都会发生相当直接的反应,在几种情况下会导致氢置换产物,而在其他系统中,光谱证据支持直接加成反应。例如,在 F 2 /H 2 S 系统中,假设最初形成 H 2 SF 2,然后在汞弧辐照下消除 HF 以形成 HSF。

the reactions F+H2S and F+D2S at 298 K were determined by a competitive method using the reaction F+CH4 as a reference reaction. The ratios of rate constants kF+H2S/kF+CH4 and kF+D2S/kF+CH4 were determined by a discharge-flow-mass spectrometric technique. By combining the values for these ratios with the value for kF+CH4 at 298 K, the values kF+H2S=(1.46±0.12)×10−10 cm3 molecule−1 s−1 and kF+D2S=(1
在298K下,反应F + H 2 S和F + D 2 S的速率常数通过竞争法使用反应F + CH 4作为参考反应来确定。速率常数k F + H 2 S / k F + CH 4和k F + D 2 S / k F + CH 4的比率通过放电流量质谱技术确定。通过将这些比率的值与在298 K时的k F + CH 4的值组合,值k F + H 2 S =(1.46±0.12)×10 -10获得了cm 3分子-1 s -1和k F + D 2 S=(1.42±0.12)×10 -10 cm 3分子-1 s -1。直接测定动力学同位素效应k F + H 2 S / k F + D 2 S并获得1.04±0.02的值。这项研究的结果与以前的文献数据进行了比较。

Protonated and deuterated samples of the hydrogensulfide of cesium were studied by high-resolution neutron powder diffraction, calorimetry and protonNMRinvestigations in a wide temperature range. Primarily due to reorientational disorder of the anions, three modifications of the title compounds are known: an ordered low-temperature modification—LTM (tetragonal, I4/m, Z=8), a dynamically disordered
