Organo-Zintl clusters soluble in conventional organic solvents: setting the stage for organo-Zintl cluster chemistry.
نویسندگان
چکیده
Organo-Zintl cluster ions were synthesized by reactions of alkynes with Ge94- clusters in ethylenediamine. The triple bonds are hydrogenated to double bonds during the process. The resulting dial-kenylated species [RHC=CHGe9CH=CHR]2- have lower charge, their alkali-metal cations can be exchanged for tetralkylammonium cations, and the resulting compounds are soluble in nonpolar solvents. This was demonstrated with [H2C=CHGe9CH=CH2]2-, which was structurally characterized with [K-(18-crown-6)]+, [Me4N]+, and [Pr4N]+ as countercations. The solubility of its salt with [Oc4N]+ in various conventional organic solvents was studied.

Water compatibility and organic transformations of organo-Zintl deltahedral clusters.
We report the remarkable stability of di-substituted organo-Zintl deltahedral clusters in the presence of water. This has been exploited in a reaction at the organic substituents of the cluster which produces water as a by-product. Also reported are the synthesis, characterization, and crystal structure of [K-krypt](2)[Ge(9)-(CH=CH-CH(2)NH(2))(2)] involved in the reaction.
متن کاملTin-based organo-Zintl ions: alkylation and alkenylation of Sn9(4-).
Reactions of nine-atom deltahedral clusters (Zintl ions) of tin, Sn 9 (4-), with alkyl chlorides, RCl (R = (t) Bu, (n) Bu, (s) Bu), and alkynes (Me3Si-C[triple bond]C-SiMe3, Ph-C[triple bond]CH) yielded the corresponding alkylated and alkenylated clusters [Sn 9-R] (3-). The triple bonds of the alkynes are hydrogenated to double bonds in the process. These are the first tin-based organo-Zintl io...
متن کاملDeveloping organo-Zintl deltahedral clusters as ligands for coordination to transition-metals via their organic tethers
Deltahedral Zintl ions Ge9 are disubstituted with organic fragments that have various functional groups. Some of the latter are appropriate for coordination to transition-metals to eventually form coordination compounds where the organo-Zintl species act as ligands. Examples of [Ge9R2] include R 1⁄4 eCH]CHIm(Me), eCH]CHeC6H4eOMe, eCH]CH-Fc, eCH]CHe(CH2)4eC^CH, eCH]CHeC6H4eC^CH, CH] CHeC6H4eNH2,...
متن کاملSynthesis of nine-atom deltahedral Zintl ions of germanium and their functionalization with organic groups.
Although the first studies of Zintl ions date between the late 1890's and early 1930's they were not structurally characterized until many years later. Their redox chemistry is even younger, just about ten years old, but despite this short history these deltahedral clusters ions E9(n-) (E = Si, Ge, Sn, Pb; n = 2, 3, 4) have already shown interesting and diverse reactivity and have been at the f...
