After a brief historical survey, the structure, main methods of preparation and reactivity of β-
lactones are examined with emphasis on developments since 1980. The structure of β …

Metal-free and metal-mediated routes for 1, 3-dipolar cycloaddition of nitrone-type dipoles to
substrates bearing the CN triple bond are compared and the reactions are categorized. In 1 …

The aromaticity and the regiochemistry of several 1, 3-dipolar cycloadditions have been
studied computationally. It is found that all the transition structures associated with concerted …

This Glossary contains definitions, explanatory notes, and sources for terms used in physical
organic chemistry. Its aim is to provide guidance on the terminology of physical organic …

This paper reports a theoretical study, at the B3LYP/6–31+ G (d, p) and M05‐2X/6–31G+(d,
p) levels, on the thermal decomposition of menthyl benzoate (2‐isopropyl‐5 …

NANO MACHINES which are of the capital aims of many advancedresearch projects would

The physical factors governing the catalysis in Lewis acid-promoted carbonyl-ene reactions
have been explored in detail quantum chemically. It is found that the binding of a Lewis acid …

Several [3+ 2] thermal cycloadditions between azomethine ylides and nitroalkenes have
been studied both theoretically and experimentally. When the N-metalated 1, 3-dipoles are …

The mechanism of the rate-limiting stage of alkanes oxidation with hydrogen peroxide, that
is, formation of the hydroxyl radicals, catalyzed by aqua complexes,[M (H2O) n] 3+(1), of the …

Ab Initio calculations (MP2/6-31G*//HF/6-31G*, including zero-point vibrational energy
(ZPVE) corrections and solvent effect) predict that the reaction between ketenes and …
