A base-promoted, efficient [3 + 2] annulation between azaoxyallyl cations and thiocarbonyls is reported for flexible access to highly functionalized thiazolidin-4-one derivatives in good to excellent yields. An intriguing feature of this method is the met

The first broad spectrum investigation into the photoenolization/Diels-Alder (PEDA) sequence was carried out using M06-2X/6-31+G(d,p) in conjunction with SMD solvation and supported by experimental UV–vis spectroscopy. A test set of 20 prodienes was chose
Composition and compound based on salt (s) of metals and of acid exhibiting a sulfonyl group carried by a perhalogenated carbon and their use as lewis acid

The present invention relates to a bismuth-type promoter and its use as a Lewis acid catalyst for acylation reactions of aromatic compounds. The promoter corresponds to the formula MYμ?qξq, where M represents a μ-valent and at least trivalent element in the cationic form, preferably known to give Lewis acids, where Y is a monovalent anion or a monovalent anionic functional group, where ξ? represents an anion or an anionic functional group carrying a sulfonyl functional group carried by a perhalogenated atom, preferably a perfluorinated atom, more preferably a perfluoromethylene (—CF2—); and where q is an integer advantageously chosen within the closed range (comprising the limits) ranging from 1 to (μ?1) (that is to say, 1 or 2 when μ is 3). The present application also relates to processes for the preparation of the promoter.
