In the wake of the aldol and Mannich reactions, textbook examples of asymmetric reactions, comes the aza‐Henry reaction (aka nitro‐Mannich reaction), which leads to 1,2‐diamines or α,β‐diaminocarboxylic acids (see scheme, PG=protecting group). A choreographer is needed to organise the performance into the ballet that is a reaction mechanism. A RUDN University chemist revised the mechanism of the Henry reaction catalyzed by copper(II) complexes. The Henry reaction (nitroaldol addition) is one of the classical C C bond-forming processes by which diastereomeric mixtures of 2-nitro alcohols are formed on treatment of primary and secondary nitroalkanes and carbonyl derivatives (more frequently aldehydes) with a base. Thus, using new copper(II) complexes obtained in the … The cross-dehydrogenative coupling (CDC) reaction of N-aryltetrahydroisoquinolines (THIQ) is one of the most exploited photocatalytic transformation and a test reaction for an exceptional variety of catalysts.

Discovered in 1895 by the Belgian chemist Louis Henry (1834-1913), it is the combination of a nitroalkane and an aldehyde or ketone in the presence of a base to form β-Nitro alcohols.
Reaction mechanism; Applications; The Perkin reaction is an organic reaction developed by William Henry Perkin that is used to make cinnamic acids. The Henry Reaction (also referred to as the nitro-aldol reaction) is a classic carbon–carbon bond formation reaction in organic chemistry. Perkin Reaction is an organic chemical reaction which was discovered by William Henry Perkin, an English chemist. The Henry reaction which is also referred to as the nitro-aldol reaction is a classic carbon–carbon bond formation reaction in organic chemistry. Yunsheng Xue, Yuhui Wang, Zhongyan Cao, Jian Zhou and Zhao-Xu Chen, Computational insight into the cooperative role of non-covalent interactions in the aza-Henry reaction catalyzed by quinine derivatives: mechanism and enantioselectivity, Organic & Biomolecular Chemistry, 10.1039/C6OB01611A, 14, 40, (9588-9597), (2016).

These are the Henry reaction and the Nef reaction. Volume 42, Issue 2. 1 Essentially, this reaction describes the coupling of a nucleophilic nitro alkane with an electrophilic aldehyde or ketone to produce a highly synthetically useful β-nitro alcohol. A green, metal- and solvent-free protocol for the aza-Henry reaction was developed by Ricci and co-workers.

The Role of H-Bonding In HQuin-BAM Catalyzed Asymmetric Aza-Henry Reactions: A DFT Study into the Reactivity, Mechanism, and Origins of Selectivity Seyedeh Maryamdokht Taimoory, M.Sc. Perkin reaction mechanism includes the reaction between aromatic aldehydes, the aliphatic acid anhydride, and the alkali salt of the acid to give cinnamic acid derivatives.

However, its mechanism remained unclear concerning involved intermediates, reactive pathways of the amine radical cation and the influence of oxygen and the light source.
