Other articles where Oxetane is discussed: heterocyclic compound: Four-membered rings: Azetidine, oxetane, and thietane—four-membered rings containing, respectively, one nitrogen, oxygen, or sulfur atom—are prepared by nucleophilic displacement reactions similar to those used to prepare the corresponding three-membered rings. Oct 15, 2009 · Using the rigid‐rotor harmonic‐oscillator approximation, this information was used to calculate the chemical thermodynamic functions, C p , S°, −(G°−H 0 )/T, H°−H 0 , and the properties of formation, Δ f H°, Δ f G°, log K f , to 1500 K in the ideal gas state at a pressure of 1 bar.

Thietane is a heterocyclic compound containing a saturated four-membered ring with three carbon atoms and one sulfur atom. [1] [2] Thietane, and its derivative 2-propylthietane, are strong-smelling mouse alarm pheromones and predator scent analogues. Petroleum spirit (which is sometimes used synonymously with petroleum ether or light petroleum) is usually less refined petroleum, and ligroin is used for fractions boiling above 100o. The lower boiling fractions consist of mixtures of n-pentane (b 36o), n-hexane (b 68.5o) and n-heptane (b 98o), and some of their isomers in varying proportions.

This group of base analogs can be used in several fluorescence investigations of nucleic acids, esp. in fluorescence anisotropy and fluorescence resonance energy transfer (FRET) measurements. Finally, the development and characterization of the first nucleic base analog FRET pair, tCO-tCnitro, and its possible future uses are discussed.

The reaction of oxetanes with Grignard reagents and organolithium compounds is well known and has been useful, particularly with oxetane itself. A recent application involves use of the reaction of isopentylmagnesium bromide with oxetane as the first step of a synthesis of an insect pheromone (equation 43) 〈76CB3375〉. The Grignard reaction with 2-methyloxetane and 2-phenyloxetane is less satisfactory, due to the extensive formation of by-products.

The chemical and configurational stability of lithiated C2-substituted thietane 1-oxides has been investigated as well as the stereochemical implications for this process. The results demonstrate that a stereoselective functionalization at the C2, C4 positions of a thietane is feasible, leaving intact the four-membered ring. The ZeroOrder method uses factor analysis with boiling point, liquid density and molecular weight as the descriptors. At the First Order, the method uses atomic contributions along with boiling point and number of rings, while the Second Order method also includes group contributions.

Thietane is a heterocyclic compound containing a saturated four-membered ring with three carbon atoms and one sulfur atom. [1] [2] Thietane, and its derivative 2-propylthietane, are strong-smelling mouse alarm pheromones and predator scent analogues. The barrier and the angle on the D-0 state, however, are found to be 48.0 cm(-1) and 18.2 degrees, respectively, where such small barrier height and puckering angle for the cation suggest that the conformation of thietane cation on the D-0 state should be more planar-than that of the thietane neutral.

A new synthetic route to N-alkyl-2-acylazetidines was developed through a highly stereoselective addition of organolithiums to N-alkyl-2-oxazolinylazetidines followed by acidic hydrolysis of the resulting oxazolidine intermediates. This study revealed an unusual reactivity of the C=N bond of the oxazoline group when reacted with organolithiums in a non-polar solvent such as toluene. The ...

The major uses of sulfur are in the heavy chemical industry; some 90% of all sulfur produced is used in the production of sulfuric acid. Sulfur dioxide is extensively employed as a preservative and antioxidant in the food industry; wine casks have been sterilised by fumigation with sulfur dioxide for thousands of years.

Thiamine is important in the breakdown of carbohydrates from foods into products needed by the body. Thiamine is used to treat or prevent vitamin B1 deficiency. Thiamine injection is used to treat beriberi, a serious condition caused by prolonged lack of vitamin B1. Thiamine taken by mouth (oral) is available without a prescription.
