We describe synthesis routes from fluorinated ethylzinc alkoxides to ether adducts of fluorinated binary homoleptic zinc alkoxides with fluorinated residues such as ORF (OC(CF3)3), ORHF (OC(H)(CF3)2), ORHT (OC(CH3)(CF3)2), ORAF (perfluoroadamantoxy) and ORCY (OC(CF3)(CF2)5). Their structures depend on the nature of the fluorinated residue: perfluorinated alkoxides ORXF tend to give monomeric ether adducts (ether)2Zn(ORXF)2, while partially fluorinated residues ORYF lead to dimers of type (ether)(YFRO)Zn(μ‐ORYF)2Zn(ORYF)(ether). The monomeric (Et2O)2Zn(ORF)2 was tested for its possibility to form fluorine doped zinc oxide upon thermal decomposition in inert atmosphere. Indeed, upon thermal degradation, homogenously doped materials (EDX mapping) with fluoride contents of 5.5 to 6 weight‐% form (EDX, ion chromatography).

The synthesis, spectroscopic and electrochemical characterization of Li[N(SiMe 3 )(SO 2 R F )] (R F = CF 3 , n-C 4 F 9 ) as well their behavior as electrolyte additive in lithium ion batteries (LIBs) is reported. The lithium salts were obtained by deprotonation of the corresponding acids HN(SiMe 3 )(SO 2 R F ) with n-butyllithium in n-pentane. The electrochemical investigations suggested poten-tial as additives for LIBs. Thus, NCM111/graphite cells (NCM111 = Li[Ni 0.33 Co 0.33 Mn 0.33 ]O 2 ) with LP57 as electrolyte (LP57 = 1.0 M LiPF 6 in EC/EMC 3 : 7) were built to test the performance. Cells with Li[N(SiMe 3 )(SO 2 R F )] as additives show coulombic efficiencies of over 99.6 %, less capacity fading over 55 cycles and a significantly lower cell impedance built up. in 3 : 7 (wt.%) EC/EMC (LP57, battery grade water content � 50 ppm, BASF®) were used. Additives used were added as weight percentage (0.25 wt.%) relating to the total mass of the electrolyte. All cells were prepared in duplicate. 4 5 6 7 8

All-cis-1,3,5-triethynyl-1,3,5-triorganyl-1,3,5-trisilacyclohexanes offer flexible scaffolds with three concordantly oriented ethynyl groups that can be lithiated and transformed into a range of other cage-like compounds, like the trimercury cage compounds [CH2Si(R)C2HgC2(R)SiCH2]3 shown in the picture.
