Sattenapally, Narsimha;Sharma, Jhanvi;Hou, Yuqing published 《Selective conversion of primary amides to esters promoted by KHSO4》 in 2018. The article was appeared in 《ARKIVOC (Gainesville, FL, United States)》. They have made some progress in their research.Synthetic Route of C9H10O2 The article mentions the following:
Primary amides, either aliphatic or aromatic, were easily converted to the corresponding esters via reflux in lower primary alcs. in the presence of KHSO4. Secondary amides led to complicated mixtures under analogous conditions, whereas tertiary amides were inert. Use of iso-Pr alc. resulted in the formation of product at slower rate and lower yield along with side products, whereas, use of tertiary alcs. did not give successful conversion and allyl and benzyl alc. provided complex mixtures And Methyl 3-methylbenzoate (cas: 99-36-5) was used in the research process.
Methyl 3-methylbenzoate (cas: 99-36-5) is a common ester.Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids.Synthetic Route of C9H10O2 Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries.
