  2. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    2 NaN 3 + 2 NaNO 2 + 4 H + → 3 N 2 + 2 NO + 4 Na + + 2 H 2 O. Above 330 °C sodium nitrite decomposes (in air) to sodium oxide, nitric oxide and nitrogen dioxide. [88] 2 NaNO 2 → Na 2 O + NO + NO 2. Sodium nitrite can also be used in the production of nitrous acid: 2 NaNO 2 + H 2 SO 4 → 2 HNO 2 + Na 2 SO 4. The nitrous acid then, under ...

  3. Nucleophilic aromatic substitution - Wikipedia

    en.wikipedia.org/wiki/Nucleophilic_aromatic...

    The following is the reaction mechanism of a nucleophilic aromatic substitution of 2,4-dinitrochlorobenzene (1) in a basic solution in water. Nucleophilic aromatic substitution Since the nitro group is an activator toward nucleophilic substitution, and a meta director, it is able to stabilize the additional electron density (via resonance) when ...

  4. Non-nucleophilic base - Wikipedia

    en.wikipedia.org/wiki/Non-nucleophilic_base

    As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile. Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.

  5. Nucleophile - Wikipedia

    en.wikipedia.org/wiki/Nucleophile

    The constant s is defined as 1 with 2-methyl-1-pentene as the nucleophile. Many of the constants have been derived from reaction of so-called benzhydrylium ions as the electrophiles: [10] and a diverse collection of π-nucleophiles: . Typical E values are +6.2 for R = chlorine, +5.90 for R = hydrogen, 0 for R = methoxy and −7.02 for R ...

    en.wikipedia.org/wiki/Catalytic_triad

    [1] [2] Catalytic triads are most commonly found in hydrolase and transferase enzymes (e.g. proteases, amidases, esterases, acylases, lipases and β-lactamases). An acid - base - nucleophile triad is a common motif for generating a nucleophilic residue for covalent catalysis .
