Zinn - Chalkogen - Heterocyclen. I. 2.4.6-Hexamethyl-1.3.5-triselena-2.4.6-tristannacyclohexan, Massen- und Schwingungsspektren

The mass spectrum of the title compound exhibits very similar fragmentation patterns compared with the sulfur analogon. The high stability of triply coordinated organotin cations is remarkable. There is no evidence for any stabilisation effects by pπ-dπ bonding concerning the ring bonds. The assignment of the vibration spectra leads to the conclusion that the molecule of triselenastanninane possesses a boat conformation.

Zinn - Chalkogen - Heterocyclen. V. 2,2,3,3,5,5,6,6-Octamethyl-1.4-dithia-2,3,5,6-tetpastan-ninan, Darstellung und Zersetzung eines Zinnreichen Heterocyclus

Abstract The title compound can be regarded as a sulfur derivative of the corresponding organoditin compound arid contains -formally- tin in the oxidation state 3. It is prepared in analogy to tris (dimethyltinsulfide).

Synthesis and Characterization of the Hybrid Clay-Based Material Montmorillonite-Melanoidin: A Potential Soil Model

The study of the interactions among metals, minerals, and humic substances is essential in understanding the migration of inorganic pollutants in the geosphere. A considerable amount of organic matter in the environment is associated with clay minerals. To understand the role of organic matter in the environment and its association with clay minerals, a hybrid clay-based material (HCM), montmorillonite (STx-1)-melanoidin, was prepared from L-tyrosine and L-glutamic acid by the Maillard reaction. The HCM was characterized by elemental analysis, nuclear magnetic resonance, x-ray photoelectron spectroscopy (XPS), scanning transmission x-ray microscopy (STXM), and thermal analysis. The presence…

Carbon-13 NMR parameters of phenyltin halogenides and phenyltin chalcogenides

The 13C NMR shift parameters and couplings to tin are reported for nine phenyltin halogenides and seven phenyltin chalcogenides, as well as the T1 results for Ph2SnTe. A pronounced linear dependence of all coupling constants on the para-carbon shift is discussed.
