Zinc triflate as Lewis acid in nucleophilic addition to cyclic N-acyliminium ions
(Georg Thieme Verlag KgStuttgartAlemanha, 2005)
Definition of a nucleophilicity scale
(AMER CHEMICAL SOC, 2006-07-06)
This work deals with exploring some empirical scales of nucleophilicity. We have started evaluating the experimental indices of nucleophilicity proposed by Legon and Millen on the basis of the measure of the force constants ...
Solvent-free microwave-promoted Michael addition of aza-nucleophiles to benzo[b] thiophen-2-yl-2-propenone
(ARKAT USA INC, 2009)
A series of Michael adducts (5-11) have been synthesized with good yields under solvent-free microwave conditions. Aliphatic and aromatic amines utilized as Michael donors reacted with 1-(4,7-dimethoxybenzo[b] thiophen-2 ...

Quantitative characterization of the global philicity patterns of common diene/dienophile pairs in cycloaddition reactions II: the interacting pair model
(Elsevier, 2015)
We present a unified model of electrophilicity and nucleophilicity that considers the electrophile/nucleophile
pair in an interacting regime, thereby avoiding the arbitrariness of defining them as the opposite
ends of a ...
Reactions of 1,2.,5-thiadiazole 1,1-dioxide derivatives with nitrogen nucleophiles. Part IV. Addition of alpha-diamines
(JOHN WILEY & SONS LTD, 2009)
alpha-diamines, such as ethylendiamine and o-phenylendiamine, add to 3,4-aryl-disubstituted 1,2,5-thiadiazole 1,1-dioxides to give dihydropyrazines or quinoxalines, respectively and sulfamide. The new compound acenaphtho ...
New dual descriptor for chemical reactivity
(AMER CHEMICAL SOC, 2005)
In this paper, a new dual descriptor for nucleophilicity and electrophilicity is introduced. The new index is defined in terms of the variation of hardness with respect to the external potential. and it is written as the ...
Addition of carbon nucleophiles to cyclic N-acyliminium ions in SDS/water
(Pergamon-elsevier Science LtdOxfordInglaterra, 2004)
Nucleophilic non-metal assited trifluoromethylation and perfluoroalkylation reactions of organic substrates
(Elsevier, 2014-01)
Nucleophilic trifluoromethylation and perfluoroalkylation reactions have been the outstanding approach during the last few decades to effect fluoroalkyl group addition or substitution reactions. In most instances, ...
