  2. Electrophile - Wikipedia

    en.wikipedia.org/wiki/Electrophile

    This reaction occurs in a similar way to the addition reaction but has an extra step in which the OSO 3 H group is replaced by an OH group, forming an alcohol: C 2 H 4 + H 2 O → C 2 H 5 OH. As can be seen, the H 2 SO 4 does take part in the overall reaction, however it remains unchanged so is classified as a catalyst. This is the reaction in ...

  3. Electrophilic addition - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_addition

    In organic chemistry, an electrophilic addition (A E) reaction is an addition reaction where a chemical compound containing a double or triple bond has a π bond broken, with the formation of two new σ bonds. [1] The driving force for this reaction is the formation of an electrophile X + that forms a covalent bond with an electron-rich ...

  4. Electrophilic amination - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_amination

    A nitrogen bound to both a good electrofuge and a good nucleofuge is known as a nitrenoid (for its resemblance to a nitrene). [2] Nitrenes lack a full octet of electrons are thus highly electrophilic; nitrenoids exhibit analogous behavior and are often good substrates for electrophilic amination reactions.

  5. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    The active site is located in the linkage between two subunits. The NADPH is involved in the generation of FADH-. In the active site, there are two cysteine residues besides the FAD cofactor and are used to break the disulphide bond during the catalytic reaction. NADPH is bound by three positively charged residues: Arg-218, His-219 and Arg-224.

  6. Electrophilic substitution - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_substitution

    This reaction is similar to nucleophilic aliphatic substitution where the reactant is a nucleophile rather than an electrophile. The four possible electrophilic aliphatic substitution reaction mechanisms are S E 1, S E 2(front), S E 2(back) and S E i (Substitution Electrophilic), which are also similar to the nucleophile counterparts S N 1 and ...

  7. Electrophilic substitution of unsaturated silanes - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_substitution...

    Since then, a number of studies have firmly established the mechanism of electrophilic attack on vinyl- and allylsilanes [4] [5] The electron-releasing strength of the carbon-silicon bond is large, and as a result, the position of silicon in the unsaturated silane controls the site of reaction and stereoselectivity. Formation of the new carbon ...

  8. Fukui function - Wikipedia

    en.wikipedia.org/wiki/Fukui_function

    The + function represents the initial part of a nucleophilic reaction. The , on the other hand, represents the initial part of an electrophilic reaction. The reaction will therefore then take place where the can be found to have a large value. Solving for either Fukui function would result in a representation of the molecule's electron density ...

  9. Directed ortho metalation - Wikipedia

    en.wikipedia.org/wiki/Directed_ortho_metalation

    In one study [13] it is found that the reaction product of N,N-dimethylaniline with a complex of TMEDA, sodium salt of TMP and di-tert-butylzinc is a meta zincated complex as a stable crystalline compound. This complex reacts with electrophilic iodine to N,N-dimethyl-3-iodoaniline: [14] Directed Meta Metallation
