881-03-8 Usage
Chemical Properties
yellow to ochre crystalline powder
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Aromatic nitro compounds, such as 2-METHYL-1-NITRONAPHTHALENE, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups. Stable under normal conditions. Protect from bases.
Fire Hazard
Flash point data are not available for 2-METHYL-1-NITRONAPHTHALENE, but 2-METHYL-1-NITRONAPHTHALENE is probably combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 881-03-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 881-03:
(5*8)+(4*8)+(3*1)+(2*0)+(1*3)=78
78 % 10 = 8
So 881-03-8 is a valid CAS Registry Number.

Corey-Chaykovsky Cyclopropanation of Nitronaphthalenes: Access to Benzonorcaradienes and Related Systems
Antoniak, Damian,Barbasiewicz, Micha?
supporting information, p. 9320 - 9325 (2019/11/19)
Nitronaphthalene derivatives react as Michael acceptors in the Corey-Chaykovsky reaction with alkyl phenyl selenones and alkyl diphenyl sulfonium salts. Mechanistic studies reveal that sterically demanding substituents at the carbanionic center favor formation of cyclopropanes and suppress competitive β-elimination to the alkylated products. The transformation, demonstrated also on heterocyclic nitroquinoline and nitroindazolines, is an example of transition metal-free dearomatization method.
A facile synthesis of 2-methylquinolines via Pd-catalyzed aza-Wacker oxidative cyclization

(Chemical Equation Presented) A novel Pd-catalyzed Wacker-type oxidative cyclization under air is described. By using this cyclization, a series of 2-methylquinolines are readily prepared with good yields under mild conditions.
