78569-36-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78569-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,6 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78569-36:
(7*7)+(6*8)+(5*5)+(4*6)+(3*9)+(2*3)+(1*6)=185
185 % 10 = 5
So 78569-36-5 is a valid CAS Registry Number.

New insight into the nature of electron delocalization: The driving forces for distorting the geometry of stilbene-like species

Yu, Zhong-Heng,Peng, Xiao-Qi

, p. 8541 - 8553 (2001)

To understand the nature of electron delocalization while questioning the abnormally large torsional angle θ of N-phenylmethylene-3-pyridineamine (6), we greatly improved our new program for energy partitioning. Meanwhile, the crystal structures of N-phen

Aerobic Oxidative Homo- and Cross-Coupling of Amines Catalyzed by Phenazine Radical Cations

Bri?ar, Rok,Unglaube, Felix,Hollmann, Dirk,Jiao, Haijun,Mejía, Esteban

, p. 13481 - 13490 (2018/11/02)

Phenazine radical cations (PhRCs) were used for the first time as efficient metal-free catalysts for the oxidative homo- and cross-coupling of a variety of different amines. A series of functional PhRCs were prepared, characterized with X-ray diffraction, and their radical character was investigated with DFT calculations. They were tested as catalysts under neat conditions with low oxygen pressure to prepare homo- and cross-coupled aliphatic and aromatic imines in high yields. Although all synthesized phenazines were catalytically active, the highest reaction rates and the best selectivity were achieved using the 5,10-dihydro-5,10-dimethylphenazine radical cation. By means of fluorescence, UV-vis and EPR spectroscopy, a mechanism of the oxidative amine coupling, catalyzed by PhRCs, is proposed.

Combination of Enabling Technologies to Improve and Describe the Stereoselectivity of Wolff-Staudinger Cascade Reaction

Musio,Mariani,?liwiński,Kabeshov,Odajima,Ley

supporting information, p. 3515 - 3526 (2016/10/18)

A new, single-mode bench-top resonator was evaluated for the microwave-assisted flow generation of primary ketenes by thermal decomposition of α-diazoketones at high temperature. A number of amides and β-lactams were obtained by ketene generation in situ and reaction with amines and imines, respectively, in good to excellent yields. The preferential formation of trans-configured β-lactams was observed during the [2+2] Staudinger cycloaddition of a range of ketenes with different imines under controlled reaction conditions. Some insights into the mechanism of this reaction at high temperature are reported, and a new web-based molecular viewer, which takes advantage from Augmented Reality (AR) technology, is also described for a faster interpretation of computed data.
