183158-34-1 Usage

Uses

Used in Polymer Industry:
2,3-Dimethylphenylboronic acid is used as a monomer for the synthesis of novel asymmetric dianhydrides, which are essential in the preparation of thermoset and thermoplastic polyimides. These polyimides are derived from asym. dianhydrides such as 2,3,3'',4'' benzophenone dianhydride (a-BTDA) and 3,4''-(hexafluoroisopropylidene)diphthalic anhydride (a-6FDA). The use of 2,3-Dimethylphenylboronic acid in this application contributes to the development of advanced materials with improved properties for various applications, including aerospace, electronics, and automotive industries.

Check Digit Verification of cas no

The CAS Registry Mumber 183158-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,1,5 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 183158-34:
(8*1)+(7*8)+(6*3)+(5*1)+(4*5)+(3*8)+(2*3)+(1*4)=141
141 % 10 = 1
So 183158-34-1 is a valid CAS Registry Number.

Method for synthesizing alpha-BPDA

-

, (2022/03/31)

The invention discloses a method for synthesizing alpha-BPDA, which comprises the following steps: by taking 2, 3-methyl bromobenzene and N-methyl-4-chlorophthalimide as raw materials, dissolving 2, 3-methylaniline in dichloromethane, salifying by adopting sulfuric acid, carrying out diazotization reaction, washing, concentrating and recrystallizing to obtain 2, 3-methyl bromobenzene, and preparing 2, 3-BPDA by adopting an Mg/tributyl borate system. The preparation method comprises the following steps: carrying out a Suzuki coupling reaction on 2, 3-methylphenylboronic acid and N-methyl-4-chlorophthalimide to obtain 5-(2, 3-dimethylphenyl)-2-methylisoindole-1, 3-diketone, carrying out alkaline hydrolysis and oxidation through a sodium hydroxide and potassium permanganate system to prepare 2, 3, 3 ', 4'-biphenyl tetracarboxylic acid, and finally forming anhydride in an o-xylene system to obtain the high-purity alpha-BPDA. According to the synthesis method, the problems of low yield and environmental pollution caused by the fact that products in a traditional method are all three isomeric mixtures are solved.

A novel method for the synthesis of substituted naphthalenes and phenanthrenes

De Koning, Charles B.,Michael, Joseph P.,Rousseau, Amanda L.

, p. 787 - 797 (2007/10/03)

A new method for the synthesis of substituted naphthalenes and phenanthrenes was discussed. A formal synthesis of tanshinone I was also studied. Natural products that contain a naphthalene or phenanthrene nucleus often exhibit biological activity, which makes them attractive targets in organic synthesis. The results showed that the reaction can be proceed through at least two different pathways.
