Perspectives on the role of the frontier effective-for-reaction molecular orbital (FERMO) in the study of chemical reactivity: An updated review

Molecular orbitals are critical in the rationalization of several chemical reactions. Thus, the frontier molecular orbital theory, proposed by Fukui?s group, postulated the importance of the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO) for chemical reactions. It should be kept in mind, however, that there are limitations of this theory and new perspectives about the chemical reactivity have recently been arisen based on composition and location of other frontier molecular orbitals. In this review, we have reported the development and the most recent applications of the Frontier Effective-for-Reaction Molecular Orbital (FERMO) concept, which describes the breaking and formation of new chemical bonds and can in turn, provide important clues that modulate chemical reactivity of atoms and molecules.

Volatile compounds of past?rma under different curing processes

The effects of different curing processes (curing temperature 4C or 10C and curing agent 150?mg/kg nitrite or 300?mg/kg nitrate) on the volatile compound profile of the past?rma (Turkish dry-cured meat product) have been investigated. A total of 45 volatile compounds, including alcohols, aldehydes, ketones, aliphatic and aromatic hydrocarbons, terpenes, sulphur compounds, esters, furans and nitrogenous compounds have been identified in past?rma samples. The curing temperature did not have a significant effect on any compound. The curing agent had statistically a significant or very significant influence on 12 compounds. In general, the use of nitrate increased the amount of volatile compound. However, lower mean hexanal value was determined in past?rma samples cured with nitrite than those cured with nitrate. Practical applications: Past?rma is a traditional dry-cured meat product. It is produced from whole muscle and/or mucsles of certain parts of beef or water buffalo carcasses. In curing stage, nitrate was used generally. However, nitrite can be used alone or with nitrate in this stage. In this study, the effects of different curing conditions (150?mg/kg nitrite or 300?mg/kg nitrate and 4C or 10C) on volatile compounds of past?rma were investigated. According to the results, past?rma produced with nitrate generally showed higher amounts of volatile compounds. On the other hand, curing temperature was not significant factor in terms of volatile compounds.

Biological studies on 1,2-benzisothiazole derivatives. VI. Antimicrobial activity of 1,2-benzisothiazole and 1,2-benzisothiazolin-3-one derivatives and of some corresponding 1,2-benzisoxazoles

Numerous 1,2-benzisothiazole and 1,2-benzisothiazolin-3-one derivatives, variously substituted in the different positions of the molecule, were tested for their in vitro antimicrobial activity. Some corresponding 1,2-benzisoxazoles and 1,2-benzisoxazolin-3-ones were also considered. Several compounds possess a potent and broad antibacterial and antifungal activity, particularly against Gram positive microorganisms, yeasts and dermatophytes. 1,2-Benzisothiazolin-3-ones were found to be the most active substances. On the contrary, the benzisoxazoles and the benzisoxazolin-3-ones considered were devoid of activity. The results obtained are discussed on the basis of structure-activity relationships.

The heavy atom structures and 33S quadrupole coupling constants of 2-thiophenecarboxaldehyde: insights from microwave spectroscopy

We report on the structures of two conformers of 2-thiophenecarboxaldehyde as obtained using a combination of molecular jet Fourier-transform microwave spectroscopy and quantum chemical calculations. The microwave spectrum was recorded using two spectrometers operating in the frequency ranges of 2.0 to 26.5 GHz and 26.5 to 40.0 GHz. The spectra of all singly-substituted heavy atom isotopologues 13C, 18O and 34S in their natural abundances could be measured and assigned to determine the gas-phase substitution rs and semi-experimental re SE structures of the most abundant conformer. The spectrum of the 33S isotopologue with its nuclear quadrupole coupling hyperfine structure was analysed, yielding the complete quadrupole tensor with high accuracy. The experimental results are used to map the observed rotational constants to the corresponding molecular structure obtained from quantum chemical calculations, which predicted two conformers with an energy difference of about 6 kJ mol?1 at the MP2/6-311++G(d,p) level of theory. Insight into the conformational stability of aromatic heterocyclic carboxaldehydes and bond situations of the sulfur atom extracted from the hyperfine structure of the 33S nucleus are discussed within the frame of the current literature. This work provides an important contribution to the study and characterisation of sulfur-containing volatile organic compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 288-16-4, you can also check out more blogs about288-16-4
