2-Naphthalenamine, N-[[4-(dimethylamino)phenyl]methylene]-, also known as N-[(4-Dimethylaminophenyl)methylene]-2-naphtylamine, is an organic compound with the chemical formula C20H19N. It is a derivative of 2-naphtylamine, featuring a naphthalene ring with an amine group at the 2-position and a phenyl ring connected through a methylene bridge, which is substituted with a dimethylamino group at the 4-position. 2-Naphthalenamine, N-[[4-(dimethylamino)phenyl]methylene]- is known for its potential applications in the synthesis of dyes and pigments, particularly in the production of certain azo dyes. It is important to note that 2-naphtylamine and its derivatives are often associated with carcinogenic properties, and thus, handling and use of such chemicals require strict safety measures and regulations.

898-02-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 898-02-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 898-02:
(5*8)+(4*9)+(3*8)+(2*0)+(1*2)=102
102 % 10 = 2
So 898-02-2 is a valid CAS Registry Number.

Rhodium-Catalyzed Dehydrogenative Annulation of N-Arylmethanimines with Vinylene Carbonate for Synthesizing Quinolines

Hu, Yan,Nan, Jiang,Yin, Jiacheng,Huang, Guanjie,Ren, Xin,Ma, Yangmin

supporting information, p. 8527 - 8532 (2021/11/13)

Here we report a novel Rh-catalyzed C-H/C-H alkenylation of N-arylmethanimines with vinylene carbonate acting as a vinylene unit. Forty examples of C3,C4-nonsubstituted quinolines were achieved from commercially available starting materials. This identified process features an exceedingly simple system, a lower loading of catalyst, and the capacity for postfunctionalization with bioactive molecules.

A stereoselective Povarov reaction leading to exo-tetrahydroindolo[3,2-c] quinoline derivatives catalyzed by iodine

Wang, Xiang-Shan,Yin, Ming-Yue,Wang, Wei,Tu, Shu-Jiang

experimental part, p. 4811 - 4818 (2012/09/22)

We report an iodine-catalyzed Povarov reaction using indole as dienophile carried out in toluene at room temperature. This three-component reaction, coupling an aldehyde, an amine, and an indole, proved to be an efficient method for synthesizing exo-indol

A study of anti-inflammatory activity of some novel α-amino naphthalene and β-amino naphthalene derivatives

Sharma, Shalabh,Singh, Tripti,Mittal, Rajan,Saxena,Srivastava, Virendra Kishore,Kumar, Ashok

, p. 145 - 152 (2007/10/03)

In the present study, some naphthalene derivatives have been synthesized by incorporating azetidinyl and thiazolidinyl moieties at its α- or β-positions such as a-(3-chloro-2-oxo-4-substitute-d)aryl-1-azetidinyl) naphthalenes 6-10, α-((substituted)aryl-4-
