Superelectrophiles and the effects of trifluoromethyl substituents.
- M. O'Connor, Kenneth N. Boblak, +4 authors D. A. Klumpp
- Chemistry, Medicine
- Journal of the American Chemical Society
- 24 February 2010
Trifluoromethyl-substituted superelectrophiles were generated in superacid (CF(3)SO(3)H), and their chemistry was examined. The strong electron-withdrawing properties of the trifluoromethyl group are… Expand
Triflic acid promoted synthesis of polycyclic aromatic compounds
- Ang Li, D. Deschepper, D. A. Klumpp
- Chemistry
- 29 April 2009
The triflic acid (CF3SO3H) promoted cyclizations of 2-styrylbiaryls are found to be useful for the synthesis of polycyclic aromatic compounds, including functionalized derivatives of polycyclic… Expand
Chemistry of dicationic electrophiles: superacid-catalyzed reactions of amino acetals.
- D. A. Klumpp, G. V. Sanchez, S. L. Aguirre, Y. Zhang, S. de Leon
- Medicine, Chemistry
- The Journal of organic chemistry
- 18 June 2002
Amino acetals are shown to form highly electrophilic systems in Bronsted superacids. It is proposed that amino acetals give dicationic electrophiles, and this proposal is supported by the direct… Expand

Preparation of 3,3-Diaryloxindoles by Superacid-Induced Condensations of Isatins and Aromatics with a Combinatorial Approach
- D. A. Klumpp, K. Y. Yeung, G. Prakash, G. Olah
- Chemistry
- 5 June 1998
3,3-Diaryloxidoles are prepared in high yields (62−99%) by reaction of isatin or substituted isatins with aromatics in triflic acid. The reaction shows a significant dependence on acid strength which… Expand
Aza-Nazarov reaction and the role of superelectrophiles.
- D. A. Klumpp, Y. Zhang, M. O'Connor, P. M. Esteves, Leonardo S de Almeida
- Medicine, Chemistry
- Organic letters
- 14 July 2007
The superacid-catalyzed reactions of N-acyliminium ion salts have been studied. The new conversions are remarkably similar to the Nazarov reaction and dicationic superelectrophilic species are… Expand
Superacid-promoted reactions of alpha-ketoamides and related systems.
- K. Sai, P. M. Esteves, E. T. da Penha, D. A. Klumpp
- Medicine, Chemistry
- The Journal of organic chemistry
- 30 July 2008
The superacid-promoted reactions of alpha-hydroxy and alpha-ketoamides have been studied. Ionization of these compounds leads to varied aryl-substituted oxyindole products. In some cases,… Expand
Charge delocalization and enhanced acidity in tricationic superelectrophiles.
