The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ) is researched.Quality Control of Silver(I) trifluoromethanesulfonate.Waters, Jessica E.; Berger, Georg; Peel, Andrew J.; Garcia-Rodriguez, Raul; Bond, Andrew D.; Wright, Dominic S. published the article 《Uncovering the Hidden Landscape of Tris(4-pyridyl) Ligands: Topological Complexity Derived from the Bridgehead》 about this compound( cas:2923-28-6 ) in Chemistry – A European Journal. Keywords: preparation tin antimony bismuth trispyridyl ligand complex; crystal structure tin antimony bismuth trispyridyl ligand complex; structure directing tin antimony bismuth trispyridyl ligand complex; coordination networks; main-group synthesis; pnictogens; topology; tripodal ligands. Let’s learn more about this compound (cas:2923-28-6).
Supramol. main group chem. is a developing field which parallels the conventional domain of metallo-organic chem. Little explored building blocks in this area are main group metal-based ligands which have the appropriate donor symmetry to build desired mol. or extended arrangements. Tris(pyridyl) main group ligands (E(py)3, E = main group metal) are potentially highly versatile building blocks since shifting the N-donor arms from the 2- to the 3-positions and 4-positions provides a very simple way of changing the ligand character from mononuclear/chelating to multidentate/metal-bridging. Here, the coordination behavior of the first main group metal tris(4-pyridyl) ligands, E(4-py)3 (E = Sb, Bi, Ph-Sn) is explored, as well as their ability to build metal-organic frameworks (MOFs). The complicated topol. of these MOFs shows a marked influence on the counteranion and on the ability of the E(4-py)3 ligands to switch coordination mode, depending on the steric and donor character of the bridgehead. This structure-directing influence of the bridgehead provides a potential building strategy for future mol. and MOF design in this area.
