Anionic Vinyl Polymerization
The concept of anionic polymerization was first developed by Ziegler and Schlenk in early 1910. Their pioneering work on the polymerization of diene initiated with sodium metal set the stage for the use of alkali metal containing aromatic hydrocarbon complexes as initiators for various α-olefins. In 1939, Scott and coworkers used for the first time the alkali metal complexes of aromatic hydroca...
متن کاملMononuclear anionic AO(2)X(3) compounds with non-VSEPR structure.
The molybdenyl compound [NBu4][MoO2(C6F5)3] () has been obtained by low-temperature treatment of MoO2Cl2 with LiC6F5 in Et2O followed by addition of [NBu4]Br. This compound of the (AO2X3)(-) type shows an unusual five-coordinate structure not lying in the Berry-pseudorotation path: it can be described rather as an edge-capped tetrahedron (TE-5). The same kind of structure has been found by DFT ...
متن کاملTrifluoperazine effects on anionic and zwitterionic micelles: a study by small angle X-ray scattering.
In this work small angle X-ray scattering (SAXS) studies on the interaction of the phenothiazine trifluoperazine (TFP, 2-10 mM), a cationic drug, with micelles of the zwitterionic surfactant 3-(N-hexadecyl-N,N-dimethylammonium) propane sulfonate (HPS, 30 mM) and the anionic surfactant sodium dodecyl sulfate (SDS, 40 mM) at pH 4.0, 7.0, and 9.0 are reported. The data were analyzed through the mo...
متن کاملSynthesis and X-ray crystal structure of an anionic heteronuclear metallamacrocyclic triangle.
trans-[Pt(C[triple bond]C(Ar)C[triple bond]CH)2(PMe3)2](Ar = C(6)Me(4)-3,4,5,6) (1) reacts with PPN[Au(acac)(2)](Hacac = acetylacetone; 1 : 1.16 molar ratio; PPN = (Ph3P)2N) to give PPN[(Au[Pt(PMe3)2]2)(mu-Ar(C[triple bond]C)2)3] (2) the crystal structure of which showed the anions as quasi equilateral triangles stacked parallel to each other through C-HAu interactions, resulting in channels of...
متن کاملSynthesis and X-ray characterization of novel palladium(II) complexes with tunable chiral anionic counterions.
Various novel palladium(II) complexes with tunable chiral and achiral anionic counterions have been prepared from dialkylpalladium(II) agents and characterized by NMR spectroscopy and X-ray diffraction.
