  2. Transition metal carboxylate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_carboxyl...

    Carboxylates bind to single metals by one or both oxygen atoms, the respective notation being κ 1 - and κ 2-.In terms of electron counting, κ 1-carboxylates are "X"-type ligands, i.e., a pseudohalide-like. κ 2-carboxylates are "L-X ligands", i.e. resembling the combination of a Lewis base (L) and a pseudohalide (X).

  3. Transition metal thiolate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_thiolate...

    Metal thiolate complexes are commonly prepared by reactions of metal complexes with thiols (RSH), thiolates (RS −), and disulfides (R 2 S 2). The salt metathesis reaction route is common. In this method, an alkali metal thiolate is treated with a transition metal halide to produce an alkali metal halide and the metal thiolate complex:

  4. Arndt–Eistert reaction - Wikipedia

    en.wikipedia.org/wiki/Arndt–Eistert_reaction

    In organic chemistry, the Arndt–Eistert reaction is the conversion of a carboxylic acid to its homologue. It is named for the German chemists Fritz Arndt (1885–1969) and Bernd Eistert (1902–1978). The method entails treating an acid chlorides with diazomethane. It is a popular method of producing β-amino acids from α-amino acids. [1]

  5. Rothemund reaction - Wikipedia

    [3] [4] This has inspired the work of his student Paul Rothemund to develop a simple one pot synthesis of porphyrins. In 1935, Paul Rothemund reported the formation of porphyrin, from a simple reaction of pyrrole with gaseous acetaldehyde or formaldehyde in methanol followed by treatment with various concentrations of hydrochloric acid .

  6. Chemical synthesis - Wikipedia

    en.wikipedia.org/wiki/Chemical_synthesis

    Medicine: Organic synthesis plays a vital role in drug discovery, allowing chemists to develop and optimize new drugs by modifying organic molecules. [9] Additionally, the synthesis of metal complexes for medical imaging and cancer treatments is a key application of chemical synthesis, enabling advanced diagnostic and therapeutic techniques. [10]

  7. Koch reaction - Wikipedia

    en.wikipedia.org/wiki/Koch_reaction

    The Koch reaction is an organic reaction for the synthesis of tertiary carboxylic acids from alcohols or alkenes and carbon monoxide.Some commonly industrially produced Koch acids include pivalic acid, 2,2-dimethylbutyric acid and 2,2-dimethylpentanoic acid. [1]

  8. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    Metals react with acids to form salts and hydrogen gas. Liberation of hydrogen gas when zinc reacts with hydrochloric acid. + () + [2] [3] However less reactive metals can not displace the hydrogen from acids. [3] (They may react with oxidizing acids though.)

    Examples from industry are the reduction of phthalic acid: and the reduction of 2-methoxynaphthalene: The Tafel rearrangement, named for Julius Tafel, was at one time an important method for the synthesis of certain hydrocarbons from alkylated ethyl acetoacetate, a reaction accompanied by the rearrangement reaction of the alkyl group: [15] [16]
