A Theoretical Study of 2-nitrofuran vs 3-nitrofuran as Dienophilic Electrophile in Polar Cycloaddition Reaction: Comparison of the Reactivity and Reaction Mechanism
(ScienceDomain international, 2016-11)
In this study, we analyzed in a theoretical form the behavior of 2-nitrofuran and 3-nitrofuran acting as dienophilic electrophiles in polar cycloaddition reactions joint to different dienes. The reactivity and regioselectivity ...
Gas-phase polar [4(+)+2] cycloaddition with ethyl vinyl ether: a structurally diagnostic ion-molecule reaction for 2-azabutadienyl cations
(John Wiley & Sons LtdChichesterInglaterra, 2003)
Further understanding of the Ru-centered [2+2] cycloreversion/cycloaddition involved into the interconversion of ruthenacyclobutane using the Grubbs catalysts from a reaction force analysis
(NLM (Medline), 2019)
The chemical reactivity of the first- and second-generation Grubbs catalysts has always been a significant issue in olefin metathesis. In the present work, we study the [2+2] cycloreversion/cycloaddition and the alkylidene ...
Quantitative characterization of the global electrophilicity pattern of some reagents involved in 1,3-dipolar cycloaddition reactions
(Elsevier, 2003)
The global electrophilicity power, ω, of a series of dipoles and dipolarophiles commonly used in 1,3-dipolar cycloadditions may be conveniently classified within a unique relative scale. The effects of chemical substitution ...
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 ...
THEORETICAL STUDY OF THE MECHANISM OF CYCLOADDITION REACTION BETWEEN DICHLORO-SILYLENE CARBENE(CL2SI=C:) AND ACETONE
(Sociedad Chilena de Química, 2010)
A molecular electron density theory study of the [3 + 2] cycloaddition reaction of nitrones with strained allenes
(Royal Society of Chemistry, 2017)
The [3 + 2] cycloaddition (32CA) reaction of C-phenyl-N-tert-butylnitrone with 1,2-cyclohexadiene (CHDE), a strained allene, has been studied within Molecular Electron Density Theory (MEDT) at the DFT B3LYP/6-311G(d,p) ...
Intramolecular azide-alkene cycloaddition-elimination reaction in an aldohex-2-enonic acid derivative
(Elsevier, 2019-09)
A 6-azido-2-tosylenolate, obtained from D-glucono-1,5-lactone in six steps, underwent an intramolecular cycloaddition–elimination pathway under mild conditions, yielding a chiral, substituted 5,6-dihydro-4H-pyrrolo ...
On the mechanism of CO2 electro-cycloaddition to propylene oxides
(Elsevier, 2016)
We herein present a systematic study on the mechanism of CO2 electro-cycloaddition to propylene oxide, using both experimental and theoretical procedures. The study considers the analysis of mild and sustainable conditions ...
