New perspectives on the reactions of metal nitrosyls with thiolates as nucleophiles
(2016-01-01)
The susceptibility of the nitrosonium ligand (NO+) of metal nitrosyls to nucleophilic attack has been reviewed. The reactions of nitroprusside with thiolate (RS-) nucleophiles (H2S, cysteine, glutathione, N-acetylcysteine ...
Suicide nucleophilic attack: Reactions of benzohydroxamate anion with bis(2,4-dinitrophenyl) phosphate
(2009-07-17)
(Chemical Equation Presented) The reaction between the benzohydroxamate anion (BHO-) and bis(2,4-dinitrophenyl)phosphate (BDNPP) has been examined kinetically, and the products were characterized by mass and NMR spectroscopy. ...

Cleaving paraoxon with hydroxylamine: Ammonium oxide isomer favors a Frontside attack mechanism
(2019-01-01)
A detailed molecular understanding of the mechanisms of the dephosphorylation of phosphate triesters due to nucleophilic attack can be very useful for the design of nucleophiles that are more efficient. In this work, we ...
Kinetics and reaction mechanism of biothiols involved in SNAr reactions: an experimental study
(Frontiers Media, 2022)
Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles ...

New reductive addition of hard nucleophiles to 6,7-bis(methylsulfanyl)-1,4-dihydro-1,4-methanonaphthalene-5,8-dione
(Royal Soc Chemistry, 2000-01-01)
A new reaction mode of 6,7-bis(methylsulfanyl)-1,4-dihydro-1,4-methanonaphthalene-5,8-dione 1 with the hard nucleophiles sodium benzene- or methane-sulfinate and cyanide, in DMSO, at room temperature, leads to the unexpected ...
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 ...
Aromatic nucleophilic substitution in nucleophilic surfactants. Comparison with alkoxide reactions
(1976)
The reactions of 2,4-dinitrochloro- and fluorobenzene (DNC and DNF) with the alkoxide ions of choline, propargyl alcohol, and 2,2,2-trifluoroethanol give ether intermediates which react readily with hydroxide ion. The ...
