939-15-1 Usage

General Description

2-Bromo-3-methylnaphthalene is a chemical compound often used in scientific or industrial processes, typically as an intermediate or catalyst in the production of other products. It belongs to the class of organic compounds known as bromonaphthalenes. This chemical is characterized by its structure, which includes a bromine atom and a methyl group attached to a naphthalene base, a polycyclic aromatic hydrocarbon comprising of two fused benzene rings. It is known for its reactivity and versatility in a variety of chemical reactions and transformations. Like many chemicals, handling it requires proper safety precautions due to its potential risks such as irritation to eyes and skin, and its potential harmfulness if inhaled or swallowed.

Check Digit Verification of cas no

The CAS Registry Mumber 939-15-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 939-15:
91 % 10 = 1
So 939-15-1 is a valid CAS Registry Number.

Synthesis of Cycloproparenes via Aromatization of 7-Oxanorbornenes with Low-Valent Titanium

Mueller, Paul,Schaller, Jean-Pierre

, p. 1608 - 1617 (2007/10/02)

1H-Cyclopropanaphthalene 3c and the 2,7-diphenyl-substituted derivative 3a have been synthesized via cycloaddition of the appropriate isobenzofurans 1a and 1b to 1-bromo-2-chlorocyclopropene and aromatization of the adducts with low-valent Ti.The same procedure afforded the 2,7-dimethyl-1H-cyclopropaisoquinoline (15), but failed for the parent azacompound.Reaction of adducts of furans to 1-bromo-2-chlorocyclopropenes with low-valent Ti produced mixtures of cyclopropabenzenes 19 and 1,6-dihalogeno-1,3,5-cycloheptatrienes 18.The latter could be converted to cyclopropabenzenes with BuLi.
