5393-49-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5393-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5393-49:
(6*5)+(5*3)+(4*9)+(3*3)+(2*4)+(1*9)=107
107 % 10 = 7
So 5393-49-7 is a valid CAS Registry Number.

α-Diimine synthesis via titanium-mediated multicomponent diimination of alkynes with C-nitrosos

Cheng, Yukun,Egger, Dominic T.,Frye, Connor W.,Kounalis, Errikos,Pearce, Adam J.,Tonks, Ian A.

, p. 1469 - 1477 (2022/02/11)

α-Diimines are commonly used as supporting ligands for a variety of transition metal-catalyzed processes, most notably in α-olefin polymerization. They are also precursors to valuable synthetic targets, such as chiral 1,2-diamines. Their synthesis is usually performed through acid-catalyzed condensation of amines with α-diketones. Despite the simplicity of this approach, accessing unsymmetrical α-diimines is challenging. Herein, we report the Ti-mediated intermolecular diimination of alkynes to afford a variety of symmetrical and unsymmetrical α-diimines through the reaction of diazatitanacyclohexadiene intermediates with C-nitrosos. These diazatitanacycles can be readily accessed in situ via the multicomponent coupling of TiNR imidos with alkynes and nitriles. The formation of α-diimines is achieved through formal [4 + 2]-cycloaddition of the C-nitroso to the Ti and γ-carbon of the diazatitanacyclohexadiene followed by two subsequent cycloreversion steps to eliminate nitrile and afford the α-diimine and a Ti oxo.
