  2. 2-Chloropyridine - Wikipedia

    en.wikipedia.org/wiki/2-Chloropyridine

    2-Chloropyridine is an aryl chloride with the formula C 5 H 4 ClN. It is a colorless liquid that is mainly used to generate fungicides and insecticides in industry. It is a colorless liquid that is mainly used to generate fungicides and insecticides in industry.

  3. Protodeboronation - Wikipedia

    en.wikipedia.org/wiki/Protodeboronation

    Protodeboronation is a well-known undesired side reaction, and frequently associated with metal-catalysed coupling reactions that utilise boronic acids (see Suzuki reaction). [1] For a given boronic acid, the propensity to undergo protodeboronation is highly variable and dependent on various factors, such as the reaction conditions employed and ...

  4. Boronic acid - Wikipedia

    en.wikipedia.org/wiki/Boronic_acid

    Boronic acids are known to bind to active site serines and are part of inhibitors for porcine pancreatic lipase, [2] subtilisin [3] and the protease Kex2. [4] Furthermore, boronic acid derivatives constitute a class of inhibitors for human acyl-protein thioesterase 1 and 2, which are cancer drug targets within the Ras cycle. [5]

  5. Organoboron chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoboron_chemistry

    Compounds of the type BR n (OR) 3-n are called borinic esters (n = 2), boronic esters (n = 1), and borates (n = 0). Boronic acids are key to the Suzuki reaction. Trimethyl borate, debatably not an organoboron compound, is an intermediate in sodium borohydride production.

  6. Pyridine-N-oxide - Wikipedia

    en.wikipedia.org/wiki/Pyridine-N-oxide

    The oxidation of pyridine can be achieved with a number of peracids including peracetic acid and perbenzoic acid. [3] Oxidation can also be effected by a modified Dakin reaction using a urea-hydrogen peroxide complex, [4] and sodium perborate [5] or, using methylrhenium trioxide (CH 3 ReO 3) as catalyst, with sodium percarbonate. [6]

  7. Borylation - Wikipedia

    en.wikipedia.org/wiki/Borylation

    The C–B bond of boronic acids and esters are slightly longer than typical C–C single bonds with a range of 1.55-1.59 Å. The lengthened C–B bond relative to the C–C bond results in a bond energy that is also slightly less than that of C–C bonds (323 kJ/mol for C–B vs 358 kJ/mol for C–C). [ 6 ]

  8. Petasis reaction - Wikipedia

    en.wikipedia.org/wiki/Petasis_reaction

    The amine is condensed with the carbonyl followed by addition of the boronic acid . [1] Alpha amino acid synthesis. One of the most attractive features of the Petasis reaction is the stability of the vinyl boronic acids. With the advent of the Suzuki coupling, many are commercially available. organoboronic acid synthesis

  9. Chloropyridine - Wikipedia

    en.wikipedia.org/wiki/Chloropyridine

    Chloropyridines are important intermediates to pharmaceuticals and agrochemicals. [1] A major use of 2-chloropyridine is the production of production of the fungicide pyrithione. Reaction of 4-chloropyridine with thioglycolic acid gives pyridylmercaptoacetic acid, a step in the production of cephalosporin antibiotics.
