83420-56-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83420-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,2 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83420-56:
(7*8)+(6*3)+(5*4)+(4*2)+(3*0)+(2*5)+(1*6)=118
118 % 10 = 8
So 83420-56-8 is a valid CAS Registry Number.

Copper-catalyzed cascade annulation between α-bromocarbonyls and biaryl or (: Z)-arylvinylacetylenes enabling a direct synthesis of dibenzocycloheptanes and related compounds

Lu, Danyang,Wan, Yimei,Kong, Lichun,Zhu, Gangguo

, p. 13971 - 13974 (2016)

Copper-catalyzed cascade annulation of γ,δ-unsaturated α-bromocarbonyls with biaryl or (Z)-arylvinylacetylenes is presented, giving an expeditious access to dibenzocycloheptanes and related compounds in moderate to high yields. It provides a novel method for the one-pot synthesis of cycloheptane and cycloheptene-fused polycyclic scaffolds featuring a rare 7-endo-trig radical cyclization.

Silver-Catalyzed Tandem C=C Bond Hydroazidation/Radical Addition/Cyclization of Biphenyl Acetylene: One-Pot Synthesis of 6-Methyl Sulfonylated Phenanthridines

Tang, Jiawei,Sivaguru, Paramasivam,Ning, Yongquan,Zanoni, Giuseppe,Bi, Xihe

, p. 4026 - 4029 (2017/08/14)

A silver-catalyzed tandem carbon-carbon triple bond hydroazidation, radical addition, and cyclization of biphenyl acetylene is described under mild conditions, leading to the formation of 6-methyl sulfonylated phenanthridines in good yields. In this novel cascade reaction, most of the atoms are incorporated into the product without cleavage of the C=C bond. Mechanistic studies suggest the reaction should proceed through an iminyl radical reactive intermediate.

Model reactions for the synthesis of azacorannulenes and related heteroaromatic compounds

Dix, Ina,Doll, Christian,Hopf, Henning,Jones, Peter G.

, p. 2547 - 2556 (2007/10/03)

4-(2-Ethynylphenyl)pyridine (10), 3-(2-ethynylphenyl)pyridine (11), 2-(2-trimethylsilylethynylphenyl)pyridine (26), and 3-ethynyl-2-phenylpyridine (13) were prepared from readily available pyridine precursors by standard coupling reactions. Pyrolysis of 10 at 810 °C/0.5 Torr provided benzo[f]isoquinoline (45) and the benzopentalene dimer 47. Pyrolysis of 11 (820 °C/0.5 Torr) afforded benzo[f]quinoline (50), benzo[h]i-soquinoline (52), and a mixture of isomers of 47. Pyrolysis of 13 (820 °C/0.3 Torr) provided benzo[h]quinoline (56) and the novel azulene derivative azuleno[1,2-b]pyridine (58). When 26 was desilylated by treatment with TBAF in THF/water, the unusual "dimerization" product 37 was produced; its structure was confirmed by X-ray structural analysis. The mechanisms of these transformations are discussed. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
