Alkane Elimination

Separate reactions of [Th{N(CH2CH2NSiMe2But)2(CH2CH2NSi(Me)(But)(μ-CH2)]2 (1) with [Re(η5-C5H5)2(H)] (2) or [Ru(η5-C5H5)(H)(CO)2] (3) produced, by alkane elimination, [Th(TrenDMBS)Re(η5-C5H5)2] (ThRe, TrenDMBS = {N(CH2CH2NSiMe2But)3}3-), and [Th(TrenDMBS)Ru(η5-C5H5)(CO)2] (ThRu), which were isolated in crystalline yields of 71% and 62%, respectively. Complex ThRe is the first example of a molecular Th-Re bond to be structurally characterised, and ThRu is only the second example of a structurally authenticated Th-Ru bond. By comparison to isostructural U-analogues, quantum chemical calculations, which are validated by IR and Raman spectroscopic data, suggest that the Th-Re and Th-Ru bonds reported here are more ionic than the corresponding U-Re and U-Ru bonds.

The electrochemical behavior of lithium-sulfur batteries was investigated by means of electrochemical impedance spectroscopy (EIS). Films of NCPEs (PEO+LiCF3SO3+BaTiO3-g-GO) were cast using a novel hot-press technique. The addition of filler in fractional amount to the solid polymer matrix at room temperature further enhances the ionic conductivity. The membranes were subjected to cycling, FT-IR and Raman spectroscopic analyses. The occurrence of ion-ion pairs interaction has been identified using FT-IR and Raman analysis. Cells with this electrolyte have a high coulombic efficiency of 98% and a high cycling stability.
