Visible-Light-Mediated Hydroacylation of Azobenzenes with α-Keto Acids

A visible-light-mediated protocol for the hydroacylation of azobenzenes with α-keto acids has been developed. In the absence of any catalyst or additive, decarboxylative hydroacylation proceeded smoothly under visible-light irradiation at room temperature. A wide range of azobenzenes and α-keto acids were well-tolerated and afforded hydroacylation products in high to excellent yields. Preliminary investigations indicated that photoactive azobenzenes absorb visible light to enable the transformation.

Amino acid-mediated Goldberg reactions between amides and aryl iodides

A highly general, experimentally simple, and inexpensive catalyst system was developed for the amidation of aryl iodides by using 5mol% of CuI as catalyst, 20mol% of an amino acid as ligand, and K3PO4 as base.

Reduction of Ag(I) by 1-acyl-2-arylhydrazines: Mechanism of photographic infectious development

The photographic process of 'infectious development' in which 1-acyl-2-arylhydrazines reduce Ag(I) has been studied using analogues. 1-Acyl-2-aryldiazenes, resulting from oxidation of 1-acyl-2-arylhydrazines, are hydrolysed to anions of aryldiazenes (ArN = NH), which undergo further oxidation with loss of nitrogen to yield aryl radicals. The aryl radicals cause 'feedback inhibition' which is prevented by the addition of benzhydrol.

Reaction of 1,2-Diarylhydrazines with Acetic Anhydride Catalyzed by 4-(Dimethylamino)pyridine

A new method for the synthesis of 1,2-diaryl-1,2-dihydro-5-methyl-3H-pyrazol-3-ones 3 and 4-acetyl-1,2-diaryl-1,2-dihydro-5-methyl-3-H-pyrazol-3-ones 5 is presented.The reaction of 4,4'-disubstituted 1,2-diarylhydrazines 1 with acetic anhydride in the presence of an equimolar amount of 4-(dimethylamino)pyridine leads to mixtures of the corresponding acetyl derivatives 2 and 3.Under the same conditions, 2,2'-disubstituted 1,2-diarylhydrazines yield mixtures of 3 and 5. Keywords.Catalysis by 4-(Dimethylamino)pyridine; 1,2-Diaryl-1,2-dihydro-5-methyl-3H-pyrazol-3-ones; 4-Acetyl-1,2-diaryl-1,2-dihydro-5-methyl-3H-pyrazol-3-ones.

NAD(P)H and Acetyl-CoA Models: Part I - Reaction of Nitrosobenzene with 1,1'-Diacetyl-1,1',4,4'-tetrahydro-4,4'-bipyridine

In vivo metabolic conditions of coenzymes NAD(P)H and acetyl-CoA may be simulated in 1,1'-diacetyl-1,1',4,4'-tetrahydro-4,4'-bipyridine (DTB) loosing hydride ion with concomitant loss of acetyl cation.This is illustrated by the formation of almost same products on treatment of nitrosobenzene with DTB as formed in vivo.The simultaneous loss of hydride and acetyl cation by DTB converts nitrosobenzene to activated labile intermediate O-acetylphenylhydroxylamine (12) which has been considered responsible for the origin of majority of products.
