Most primary and secondary perfluoroalcohols are unstable, for example trifluoromethanol eliminates hydrogen fluoride, forming carbonyl fluoride. [2] This reaction is reversible. [3] CF 3 OH → COF 2 + HF. Stable perfluorinated alcohols include nonafluoro-tert-butyl alcohol ((CF 3) 3 COH) and pentafluorophenol (C 6 F 5 OH).
Fluorination with aminosulfuranes is a chemical reaction that transforms oxidized organic compounds into organofluorine compounds.Aminosulfuranes selectively exchange hydroxyl groups for fluorine, but are also capable of converting carbonyl groups, halides, silyl ethers, and other functionality into organofluorides.
Benzyl alcohol (also known as α-cresol) is an aromatic alcohol with the formula C 6 H 5 CH 2 OH. The benzyl group is often abbreviated "Bn" (not to be confused with "Bz" which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor.
The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines. The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually between 120 and 130 °C; for the ...
Under ideal conditions the reaction produces 50% of both the alcohol and the carboxylic acid (it takes two aldehydes to produce one acid and one alcohol). [5] This can be economically viable if the products can be separated and both have a value; the commercial conversion of furfural into furfuryl alcohol and 2-furoic acid is an example of this ...
Friedel–Crafts reactions have been used in the synthesis of several triarylmethane and xanthene dyes. [26] Examples are the synthesis of thymolphthalein (a pH indicator) from two equivalents of thymol and phthalic anhydride: A reaction of phthalic anhydride with resorcinol in the presence of zinc chloride gives the fluorophore fluorescein.
The Achmatowicz reaction, also known as the Achmatowicz rearrangement, is an organic synthesis in which a furan is converted to a dihydropyran.In the original publication by the Polish chemist Osman Achmatowicz Jr. (b. 20 December 1931 in Vilnius) in 1971 [1] furfuryl alcohol is reacted with bromine in methanol to 2,5-dimethoxy-2,5-dihydrofuran which rearranges to the dihydropyran with dilute ...
[6] [7] According to McQuade, the reaction between methyl acrylate and p-nitrobenzaldehyde is second-order relative to the aldehyde. Moreover, it showed a significant kinetic isotope effect for the acrylate's α-hydrogen (5.2 in DMSO , but ≥2 in all solvents), which would imply that proton abstraction is the rate-determining step.
