Anti-Markovnikov Hydroamination of Alkenes with …

In organic chemistry, hydroamination is the addition of an N−H bond of an amine across a carbon-carbon multiple bond of an alkene, alkyne, diene, or allene. In the ideal case, hydroamination is atom economical and green. Amines are common in fine-chemical, pharmaceutical, and agricultural industries. … Meer weergeven Hydroamination is well-established technology for generating fragrances from myrcene. In this conversion, diethylamine adds across the diene substituent, the reaction being catalyzed by lithium diethylamide. … Meer weergeven Hydroamination reactions are atom-efficient processes that generally use readily available and cheap starting materials, … Meer weergeven The hydroamination reaction is approximately thermochemically neutral. The reaction however suffers from a high activation barrier, perhaps owing to the repulsion of … Meer weergeven Certain titanium and zirconium complexes catalyze intermolecular hydroamination of alkynes and allenes. Both stoichiometric and catalytic … Meer weergeven Hydroamination has been examined with a variety of amines, unsaturated substrates, and vastly different catalysts. Amines that have been … Meer weergeven Strong bases catalyze hydroamination, an example being the ethylation of piperidine using ethene: Such base … Meer weergeven The addition of hydrogen and an amino group (NR2) using reagents other than the amine HNR2 is known as a "formal hydroamination" reaction. Although the advantages of atom economy and/or ready available of the nitrogen source are diminished … Meer weergeven Web15 aug. 2024 · Hydroamination is a reaction that involves the addition of a hydrogen and an amino group across an unsaturated C-C bond, such as that in alkenes or in alkynes. It is a form of hydrofunctionalization with the functional group being an amine or amino derivative. Hydroamination is most often performed catalytically.
