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.

Ab initio HF, density functional and experimental studies on the IR spectra and structure of 1,2-benzisothiazol-3-(2H)-thione-1,1-dioxide (thiosacchanin) and its nitranion

The spectral and structural changes taking place in the course of the conversion of 1,2-benzisothiazol-3-(2H)-thione-1,1-dioxide (thiosaccharin) into a nitranion have been studied on the basis of both IR spectra and ab initio HF 6-31G(d) and BLYP 6-31G(d,p) force field calculations. The conversion causes nuSO(2)as and nuSO(2)s frequency decreases of 47 and 13 cm-1, respectively, and other spectral changes. The nuC double bond S coordinate is strongly delocalized. The ab initio geometries of the isolated molecule and nitranion agree well with the single-crystal X-ray ones, determined for thiosaccharin and its sodium (potassium) monohydrate salts, respectively. The nitranionic charge is delocalized almost uniformly within the thiocarbonyl (0.29 e-), sulfonyl (0.24 e-), and phenylene (0.24 e-) groups, and the nitranionic center (0.23 e-).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 27148-03-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 27148-03-4, in my other articles.

Optimization studies of microwave-induced co-pyrolysis of empty fruit bunches/waste truck tire using response surface methodology

The central composite design of RSM was utilised for the optimization of experimental conditions of microwave-assisted co-pyrolysis of empty fruit bunch (EFB) and waste truck-tire (TT) to maximise the co-pyrolysis oil and energy yield. The predicted maximum co-pyrolysis oil of 40.0 wt% and energy yield of 59.0% were obtained at the optimum conditions of 505 C pyrolysis temperature, 65.0% of EFB ratio and 60.0 g of activated carbon loading. The reaction temperature and TT ratio in EFB feedstock were identified as the most significant variables that affect the oil and energy yield. A design of experiment was performed to determine the quality of liquid oil. The result indicates the co-pyrolysis oil (PO65) properties were significantly improved after adding TT to EFB biomass. Olefin-rich pyrolytic oil (39.0%) with high selectivity of D-limonene was produced (28.6%). While, the oxygenates and polyaromatics hydrocarbon were reduced to 9.9% and 7.4%, respectively. The energy recovery analysis shows that the optimised co-pyrolysis oil (PO65) was 20.0% higher as compared to the TT alone. In view of the improved yield and quality of co-pyrolysis oil (PO65), this work shows that co-pyrolysis of EFB/TT presents a viable method to produce diesel-like fuel using the microwave-assisted heating method.

THE N-H STRETCHING REGION OF SOME IMIDES AND THIOIMIDES

The multiplet structure of nuN-H and nuN-D bands of solid phthalimide, monothiophthalimide, dithiophthalimide, isatin, saccharin and of their deuterated analogues has been explained as being a result of Fermi resonance of the fundamentals of nuN-H ans nuN-D with combinations and/or overtones.The submaxima of 3080 and 2970 cm-1 of saccharin as well as pronounced doublet at 2465 and 2345 cm-1 of d-phthalimide move to lower frequency in the low temperature ir spectra, while the “windows” remain fixed at 3045 and 2380 cm-1, respectively.These examples could be a striking demonstration of Evans type Fermi resonance.
