2531-84-2 Usage

Uses

2-Methylphenanthrene is a polycyclic aromatic hydrocarbon pollutant from polystyrene plastic.

General Description

White crystalline solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as 2-METHYLPHENANTHRENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. 2-METHYLPHENANTHRENE may be sensitive to prolonged exposure to light.

Fire Hazard

Flash point data for 2-METHYLPHENANTHRENE are not available. 2-METHYLPHENANTHRENE is probably combustible.

Check Digit Verification of cas no

The CAS Registry Mumber 2531-84-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,3 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2531-84:
(6*2)+(5*5)+(4*3)+(3*1)+(2*8)+(1*4)=72
72 % 10 = 2
So 2531-84-2 is a valid CAS Registry Number.

Hydrous pyrolysis of methylphenanthrenes - Degradation and isomerization

Wu, Suh-Huey,Wang, Yane-Shih,Fan, Lian-Xin,Robert, T. D. Chang,Huang, Ded-Shih

, p. 315 - 317 (2002)

A simulation of the chemical transformations of methylphenanthrenes in sediment was performed using hydrous pyrolysis technique. The results indicate that isomerization is not the primary cause of the change in the MPI1 index. Rather, the degradation reaction of methylphenanthrenes to phenanthrene is one of the most likely causes reversing the trend of the MPI1 index with increasing the heating temperature. An unusual isomerization between 2-methylphenanthrene and 9-methylphenanthrene was also observed during the course of heating experiments. A plausible mechanism involving [1,5]-methyl shift was proposed for this isomerization reaction.

A New Parameter for Maturity Assessment of Organic Materials in Sediments Based on Thermal Isomerization of Monomethylphenanthrenes

Shimoyama, Akira,Nakano, Yoshinobu,Nomoto, Shinya

, p. 1917 - 1920 (1994)

Monomethylphenanthrenes(MPs) were isomerized by heating in the presence of Na-montmorillonite to give a mixture of four isomers (1-, 2-, 3-, and 9-MP).The ratio of 1- and 2-MP produced from each isomer reached a constant value after appropriate time of heating.The ratio provides a new parameter for maturity assessment of sedimentary organic materials.

Alumina-Mediated π-Activation of Alkynes

Akhmetov, Vladimir,Amsharov, Konstantin,Feofanov, Mikhail,Sharapa, Dmitry I.

, p. 15420 - 15426 (2021/09/30)

The ability to induce powerful atom-economic transformation of alkynes is the key feature of carbophilic π-Lewis acids such as gold- and platinum-based catalysts. The unique catalytic activity of these compounds in electrophilic activations of alkynes is explained through relativistic effects, enabling efficient orbital overlapping with π-systems. For this reason, it is believed that noble metals are indispensable components in the catalysis of such reactions. In this study, we report that thermally activated γ-Al2O3activates enynes, diynes, and arene-ynes in a manner enabling reactions that were typically assigned to the softest π-Lewis acids, while some were known to be triggered exclusively by gold catalysts. We demonstrate the scope of these transformations and suggest a qualitative explanation of this phenomenon based on the Dewar-Chatt-Duncanson model confirmed by density functional theory calculations.

Construction of Phenanthrenes and Chrysenes from β-Bromovinylarenes via Aryne Diels-Alder Reaction/Aromatization

Singh, Vikram,Verma, Ram Subhawan,Khatana, Anil K.,Tiwari, Bhoopendra

, p. 14161 - 14167 (2019/10/28)

A highly efficient transition-metal-free general method for the synthesis of polycyclic aromatic hydrocarbons like phenanthrenes and chrysenes (and tetraphene) from β-bromovinylarenes and arynes has been developed. The reactions proceed via an aryne Diels-Alder (ADA) reaction, followed by a facile aromatization. This is the first report on direct construction of chrysenes (and tetraphene) using the ADA approach. Unlike the literature method which is limited to only 9/10-substituted derivatives, this method gives access to a wide variety of functionalized phenanthrenes.

Further insight into the photochemical behavior of 3-aryl-N-(arylsulfonyl)propiolamides: tunable synthetic route to phenanthrenes

Chen, Ming,Zhao, Xinxin,Yang, Chao,Wang, Yanpei,Xia, Wujiong

, p. 12022 - 12026 (2017/03/01)

Reported herein is further insight into the photochemical behaviour of 3-aryl-N-(arylsulfonyl)-propiolamides, which provides a straightforward way to access meaningful phenanthrenes. Mechanistic investigation indicated that aryl migration, C-C coupling, 1,3-hydrogen shift, desulfonylation and elimination were involved in the process. Moreover, this protocol allowed for scale-up using a flow reactor.
