Tellurium-nitrogen-containing heterocycles

This chapter focuses on the tellurium-nitrogen-containing heterocycles. More than 20 diverse structural types of the heterocycles containing tellurium and nitrogen atoms in a ring have become known, most having been studied during the last decade. Both the methods for the preparation and the reactions of tellurium-nitrogen-containing heterocycles differ from those characteristic of their sulfur and selenium analogues. Owing to the higher nucleophilicity of Te (II) centers, tellurium heterocycles readily form telluronium salts and give stable complexes even with relatively soft Lewis acids. In tellurium heterocycles, Te (II) centers are capable of forming intramolecular and intermolecular coordination bonds with oxygen and nitrogen centers that are stronger than the bonds formed by other chalcogen centers. This property of organotellurium compounds is responsible for the peculiar physical characteristics of benzoisotellurazole, 1,2,5-telluradiazole, and some other tellurium-nitrogen-containing heterocycles. Heterocycles with one tellurium (Te)atom and one nitrogen (N) atom include isotellurazoles, their benzo fused derivatives, and benzotellurazoles. Derivatives of three of the four possible structural types of heterocycles with one Te atom and two N atoms have been synthesized and discussed in the chapter. The chapter also discusses heterocycles containing other elements in the ring along with Te and N atom, tellurium- and nitrogen-containing macrocycles, and tellurium-containing heterocycles with N-bridged atoms.

New data on vanillin-based isothiazolic insecticide synergists

By alkylation of vanillin with 4,5-dichloro-3-chloromethylisothiazole the corresponding ether was synthesized. The latter was then reacted with p-Toluidine to afford the corresponding azomethine. During the bioassays of synthesized isothiazolic derivatives of vanillin in mixtures with insecticides (imidacloprid and alpha-cypermethrin) a strong synergetic effect was observed.(Diagram Parented).

Molecular structure and infrared spectra of the monomeric 3-(methoxy)-1,2-benzisothiazole 1,1-dioxide (methyl pseudosaccharyl ether)

The computational description of saccharin (1,2-benzisothiazol-3(2H)-one-1,1-dioxide) and its derivatives is difficult due to the presence of hypervalent S{double bond, long}O bonds in their structures. Therefore, in this investigation, the HF, DFT/B3LYP and MP2 methods were used to predict the geometry and the infrared spectrum of the saccharyl derivative 3-(methoxy)-1,2-benzisothiazole 1,1-dioxide (MBID). Their relative predictive capabilities were then evaluated by comparing the obtained results with experimentally available data, namely the newly obtained IR spectra of MBID isolated in low-temperature inert matrices. For each method, different basis sets [6-31++G(d,p), 6-31++G(3df,3pd), 6-311++G(d,p), 6-311++G(2df,2pd), 6-311++G(3df,3pd), aug-cc-pVDZ and aug-cc-pVTZ] were considered. The best overall agreement has been achieved at the B3LYP/6-311++G(3df,3pd) and B3LYP/6-31++G(3df,3pd) levels of theory, showing the adequacy of the B3LYP functional to describe the investigated properties in this type of compounds and stressing the relevance of including high-order polarization functions in the basis set. The chosen level of theory [B3LYP/6-311++G(3df,3pd)] was applied to analyze the vibrational spectra and the geometry of the title molecule. In agreement with the experiment, the C{single bond}O{single bond}C linkage in MBID is predicted by these calculations to exhibit considerably short (1.320 A) and long (1.442 A) (N{double bond, long})C{single bond}O and (H3)C{single bond}O bonds, respectively, and a hybridization of the central oxygen atom close to sp2 (the C{single bond}O{single bond}C angle is predicted to be ca. 117). This C{single bond}O{single bond}C bonding pattern fits the well-known high reactivity of MBID upon thermal rearrangement, which has been shown to result in easy selective [1,3?]-isomerization of the compound.

Release of volatile organic compounds by oxidative wear of automotive friction materials

Contribution of friction processes to the environmental pollution was proven in several studies, especially with respect to release of particulate emissions containing metals. Not too many researchers pay attention to volatile organic compounds formation during braking, although it is very relevant topic. When organic friction materials are used, the oxidative processes and thermal degradation always accompanies the friction processes during braking. A low-metallic, brake lining formulation was tested using the ISO 26867 friction evaluation standard procedure in an automotive full-scale brake dynamometer. Sampling of non-airborne debris, suspended airborne particles (PM10) and air was performed directly in the environmental chamber. Released volatiles and semi volatile organics were analyzed using GC/MS, Pyr/GC/MS, FTIR and carbon phase analysis. Occurrence of important groups of volatile organic compounds as PAHs and BTEXs with possible adverse effects on living organisms was confirmed.

Gas phase basicities of polyfunctional molecules. Part 6: Cyanides and isocyanides

This paper gathers structural and thermochemical informations related to the gas-phase basicity of molecules containing cyanides (nitriles) and isocyanides (isonitriles) functional groups. It constitutes the sixth part of a general review devoted to gas-phase basicities of polyfunctional compounds. A large corpus of cyanides and isocyanides molecules is examined under seven major chapters. In the first one, a rapid overview of the definitions and methods leading to gas-phase basicity, GB, proton affinity, PA, and protonation entropy, DeltapS, is given. In the same chapter, several aspects of the gas phase chemistry of protonated cyanides and isocyanides are also presented. Chapters II-VI detail the protonation energetics of aliphatic, unsaturated, and heteroatom substituted (halogens, O, S, N, P) cyanides. A seventh chapter is devoted to isocyanides. Experimental data available in the literature (120 references) were reevaluated according to the presently adopted basicity scale that is the NIST database anchored to PA(NH3) = 853.6 kJ/mol and GB (NH3) = 819 kJ/mol. In this latter source, however, several erroneous values have been identified which were corrected in the present review. Structural and energetic information given by G4MP2 quantum chemistry computations on ca. 60 typical systems are presented. The present review includes the GB, PA, and DeltapS values of ca. 110 cyanides and isocyanides, and, for selected examples, is completed by a set of computed heats of formation (DeltafH) at 0 and 298 K.
