Reaction of iodonium ylides of 1,3-dicarbonyl compounds with HF reagents.
Reaction of dibenzoylmethane with (diacetoxyiodo)benzene in the presence of KOH in MeCN quantitatively gave the corresponding iodonium ylide, which was treated with a HF reagent to afford the corresponding 2-fluorinated dibenzoylmethane in 14-50% yields. The similar reaction of the iodonium ylides obtained from 1-phenylbutan-1,3-dione, ethyl benzoylacetate, and ethyl p-nitrobenzoylacetate with ...
متن کاملAn ab Initio Investigation of Halocarbenes
Gaussian-2 and QCI theory with basis sets up to 6-311+G(3df,2p) have been employed to obtain information about the carbenes (methylenes) CH2, CHBr, CHCl, CHF, CHI, CBr2, CBrCl, CBrF, CBrI, CCl2, CClF, CClI, CF2, and CI2. Geometries and vibrational frequencies for the singlet and triplet states, and the singlet-triplet splittings, have been characterized and are discussed in the context of the e...
متن کاملMechanically induced solid-state generation of phosphorus ylides and the solvent-free Wittig reaction.
We describe the nearly quantitative preparation of phosphorus ylides and the Wittig reaction occurring in the solid sate during high-energy mechanochemical processing. Initial insights into the details of the discovered chemical transformations indicate that high-energy mechanical processing supports the interaction of reacting centers by breaking crystallinity of the reactants and by providing...
متن کاملREACTION OF QUINONEIMINES WITH KETENES
The reactivity of quinoneimines towards ketene and diphenylketene was examined. N-Phenylbenzoquinoneirnines (I), (2) and also N-phenylnaphthoquinoneimine react with ketene to give the spiro-adducts (5), (7) and (1 1) respectively. These adducts were stable even after prolonged heating in high boiling solvent. Reaction of the above imines with diphenylketene also afforded 13- lactam spiro-a...
متن کاملAsymmetric 1,3-dipolar cycloadditons of stabilized azomethine ylides with nitroalkenes.
This review highlights the biological importance of many polysubstituted nitro-prolines and -pyrrolidines. Their preparation using asymmetric 1,3-dipolar cycloadditions of azomethine ylides with nitroalkenes using diastereoselective and enantioselective strategies is described remarking the scope and main features of each one.
