Usage

General Description

ETHYL 2-OCTYNOATE, also known as oct-2-ynoic acid ethyl ester, is an organic chemical compound that falls under the category of alkynyl non-terpenoid derivatives. Its chemical formula is C10H16O2, and it appears as a clear, colourless to yellowish liquid. It is often used in the flavour and fragrance industry due to its fruity and cognac-like characteristics. Due to its organic nature, it is usually developed as a synthetic compound. Despite its industrial uses, caution is recommended in handling this chemical due to its potential impact on human health and the environment.

cis-Semihydrogenation of alkynes with amine borane complexes catalyzed by gold nanoparticles under mild conditions

Supported gold nanoparticles catalyze the semihydrogenation of alkynes to alkenes with ammonia borane or amine borane complexes in excellent yields and under mild conditions. Internal alkynes provide cis-alkenes, making this protocol an attractive alternative of the classical Lindlar's hydrogenation.

Deuteration of α,β-acetylenic esters, amides, or carboxylic acids without using deuterium gas: Synthesis of 2,2,3,3-tetradeuterioesters, amides, or acids

An easy, simple, rapid, and nonhazardous deuteration of the C-C triple bond of α,β-acetylenic esters, amides, or acids by means of samarium diiodide in the presence of D2O, provides an efficient method for synthesizing 2,2,3,3-tetradeuterioesters, amides, or carboxylic acids, respectively. When H2O is used instead of D2O, saturated carboxylic esters, amides, or acids were isolated. A mechanism to explain these reduction reactions has been proposed.

(Ethoxycarbonyliodomethyl)triphenylphosphonium Iodide: A Convenient Reagent for the Direct Synthesis of β-Substituted Propiolic Acids via the Corresponding Esters

Reaction between (ethoxycarbonyliodomethyl)triphenylphosphonium iodide, potassium carbonate, and various aromatic or aliphatic aldehydes in a liquid solid two phases system gives β-substituted propiolic esters.The corresponding acids are obtained in good yield by hydrolysis.
