729-43-1 Usage

General Description

Acetophenone Azine is a chemical compound that is categorized under the class of azines, which are organic compounds containing two or more compounds where three nitrogen atoms are each attached to the other one. The compound exists as a light yellow crystalline powder that appears needle-like, which has a specific pungent smell. Being light-sensitive, it should be stored in a dark place. It has a melting point of 72-75°C and a boiling point of around 168-169°C. Acetophenone Azine is primarily used in the production of pharmaceuticals, organic synthesis, and as a preservative in perfumery. It requires careful handling due to its potential health hazards such as skin and eye irritation. Its chemical formula is (C6H5COCH3)2N2.

Check Digit Verification of cas no

The CAS Registry Mumber 729-43-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 729-43:
(5*7)+(4*2)+(3*9)+(2*4)+(1*3)=81
81 % 10 = 1
So 729-43-1 is a valid CAS Registry Number.

Gold(I) complexes bearing ring-fused benzoxazine-derived triazolylidenes and their use in C–N bond-forming processes

Campos-Dominguez, Emmanuel,Vasquez-Perez, Jose,Rojas-Lima, Susana,Lopez-Ruiz, Heraclio,Mendoza-Espinosa, Daniel

, (2020/12/07)

We report the synthesis and full characterization of a novel series of ring-fused benzoxazine-derived triazolium salts (1a–c) and their corresponding triazolylidene gold(I) complexes (2a–c). All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and mass spectroscopy and in the case of triazoliums 1a and 1b by single-crystal X-ray diffraction. The new triazolylidene gold complexes (2a–c) were tested as precatalysts in the hydroamination and hydrohydrazination of terminal alkynes employing aniline derivatives and hydrazine as nitrogen sources, respectively.

Synthesis of Sterically Hindered Primary Amines by Concurrent Tandem Photoredox Catalysis

Primary amines are an important structural motif in active pharmaceutical ingredients (APIs) and intermediates thereof, as well as members of ligand libraries for either biological or catalytic applications. Many chemical methodologies exist for amine synthesis, but the direct synthesis of primary amines with a fully substituted α carbon center is an underdeveloped area. We report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. We also demonstrate that this method enables the synthesis of amines with α-trifluoromethyl functionality. Based on experimental and computational results, we propose a mechanism where the photocatalyst engages in concurrent tandem catalysis by reacting with the oxime as a triplet sensitizer in the first catalytic cycle and a reductant toward the cyanoarene in the second catalytic cycle to achieve the synthesis of hindered primary amines via heterocoupling of radicals from readily available oximes.

Rapid and Atom Economic Synthesis of Isoquinolines and Isoquinolinones by C–H/N–N Activation Using a Homogeneous Recyclable Ruthenium Catalyst in PEG Media

Deshmukh, Dewal S.,Gangwar, Neha,Bhanage, Bhalchandra M.

supporting information, p. 2919 - 2927 (2019/05/10)

Herein, we report an atom-efficient, rapid, green, and sustainable approach to synthesize isoquinolines and isoquinolinones using a homogeneous recyclable ruthenium catalyst in PEG Media assisted by microwave energy. Dibenzoylhydrazine was used for C–H/N–N activation reactions for the first time in combination with ketazine as oxidizing directing groups for annulation reactions with internal alkynes. The developed protocol is environmentally benign due to significantly shortened times with an easy extraction method, higher atom economy, external oxidant and silver or antimony salt free conditions, applicability to a gram scale synthesis, use of biodegradable solvent and wide substrate scope with higher product yields. Moreover, it is worth noting that the established methodology allowed reuse of the catalytic system for up to five successive runs with minimal loss in activity.
