The solutions of the nucleophiles
in EG (Nu/EG solution) were prepared by dissolving the salt of each nucleophile
in EG according to a molar Nu/Cl ratio between 0 and 8.
2006; Goze & Ziessel 2007), ethynyl nucleophiles
reveal that only the disubstituted product can be produced when using a lithium reagent (Scheme 2), while either the monosubstituted or disubstituted product can be produced when using a Grignard reagent (Scheme 3).
The electrophilic character of the central carbon in isothiocyanate is usually explored as a reactive group for biologic nucleophiles
It is also widely accepted that at alkaline pH, the curing rate of phenolic nuclei as nucleophiles
is strengthened by ionization of the phenol to form phenolate ions.
A higher (or less nve) HOMO energy corresponds to the more reactive molecule in reaction with electrophiles, while lower LUMO energy is essential for molecular reaction with nucleophiles
On the other hand, the siloxane bond is highly susceptible to heterolytic cleavage from reactions with nucleophiles
The ambient cathodically generated nucleophiles
alkylate at both carbon and oxygen and the competition is crucially dependent on the cation (tetra-butylammonium ion or lithium ion).
If dietary exposure cannot be prevented, secondary prevention, defined as preventing the carcinogen from reaching its target or interacting with tissue nucleophiles
, could be considered.
1) The esters are also known to undergo facile reaction with a variety of nucleophiles
Being a transition metal cation, Cu(II) has a high affinity to nucleophiles
such as carboxylics and amines.
The first covers the introduction of nitrogen-containing functional groups by amination of carbon-based nucleophiles
Considering that quinone methides are the resonance hybrids between the quinoid and benzenoid structures, and their high reactivity to electrophiles and nucleophiles
, it is evident that the polycondensation mechanism in all catalytic conditions can be explained by their participation.
