7099-88-9 Usage

General Description

4-Chlorobenzoylformic acid is a chemical compound belonging to the class of organic compounds known as chlorobenzenes, classified under aromatic compounds. Being a derivative of benzoic acid, it has a chlorine atom substituted onto its benzene ring and a carboxylic acid group attached to it. This chemical usually comes as a crystalline powder with a molecular formula of C8H5ClO3. Its potential uses are largely in chemical synthesis and industrial applications due to its reactivity. The acid can also serve as a useful reagent in the manufacture of various drugs, dyes, and polymers. Its potential health effects and environmental impacts should be controlled within proper safety guidelines and protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 7099-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7099-88:
(6*7)+(5*0)+(4*9)+(3*9)+(2*8)+(1*8)=129
129 % 10 = 9
So 7099-88-9 is a valid CAS Registry Number.

Synthesis of α-Keto Acids via Oxidation of Alkenes Catalyzed by a Bifunctional Iron Nanocomposite

Song, Tao,Ma, Zhiming,Wang, Xiaoxue,Yang, Yong

supporting information, p. 5917 - 5921 (2021/07/31)

An efficient methodology for synthesis of α-keto acids via oxidation of alkenes using TBHP as oxidant catalyzed by a bifunctional iron nanocomposite has been established. A variety of alkenes with different functional groups were smoothly oxidized into their corresponding α-keto acids in up to 80% yield. Moreover, the bifunctional iron nanocomposite catalyst showed outstanding catalytic stability for successive recycles without appreciable loss of activity.

Photoinduced homolytic decarboxylative acylation/cyclization of unactivated alkenes with α-keto acid under external oxidant and photocatalyst free conditions: access to quinazolinone derivatives

Sun, Bin,Shi, Rongcheng,Zhang, Kesheng,Tang, Xiaoli,Shi, Xiayue,Xu, Jiayun,Yang, Jin,Jin, Can

supporting information, p. 6050 - 6053 (2021/06/21)

A novel and green strategy for the synthesis of acylated quinazolinone derivativesviaphoto-induced decarboxylative cascade radical acylation/cyclization of quinazolinone bearing unactivated alkenes has been developed. The protocol provides a novel route to access acyl radicals from α-keto acids through a self-catalyzed energy transfer process. Most importantly, the reaction proceeded smoothly without any external photocatalyst, additive or oxidant, and could be easily scaled-up in flow conditions with sunlight irradiation.

Possible competitive modes of decarboxylation in the annulation reactions ofortho-substituted anilines and arylglyoxylates

Laha, Joydev K.,Panday, Surabhi,Tomar, Monika,Patel, Ketul V.

supporting information, p. 845 - 853 (2021/02/09)

Annulation reactions ofortho-substituted anilines and arylglyoxylates in the presence of K2S2O8at 80 °C under metal-free neutral conditions have been investigated, which extended a platform for the tandem synthesis of nitrogen heterocycles. While arylglyoxylic acids are known to undergo decarboxylation to form an acyl radical in the presence of K2S2O8and used in the Minisci acylation of electron-deficient (hetero)aromatics, their reactions with electron-richortho-substituted anilines to form nitrogen heterocycles have recently been studied. Depending upon the experimental conditions used in the reactions, the mechanism of the formation of heterocycles involving reactions of an acyl radical or aryl iminocarboxylic acids has been postulated. Given the subtle understanding of the mechanisms of annulation reactions of 2-substituted anilines and arylglyoxylates in the presence of K2S2O8, an extensive mechanistic investigation was undertaken. In the current study, the various mechanistic pathways including the generation of acyl, imidoyl, aminal, and N,O-hemiketal radicals have been postulated based on different possible decarboxylation modes. Some of the proposed intermediates are supported based on the available analytical data. The protocol uses a single, inexpensive reagent K2S2O8, which offers not only transition-metal-free conditions but also serves as the reagent for the key decarboxylation step. Taken together, this study complements the current development of the annulation reactions of 2-substituted anilines and arylglyoxylates in terms of synthesis and mechanistic understanding.
