CH3CHCHCOOR

CH3CHCHCOOR is a chemical compound with the formula (CH3)2CHCH(COOR), where R is an alkyl or aryl group. It is a derivative of 3-buten-2-one, with an ester group attached to the ketone functionality. The compound is known as a β-keto ester, a class of compounds that exhibit interesting chemical properties and potential applications in organic synthesis.

The structure of CH3CHCHCOOR consists of a linear alkyl chain with a double bond between the second and third carbon atoms, a ketone group at the third carbon, and an ester group at the first carbon. The ester group is formed by the reaction of 3-buten-2-one with an alcohol in the presence of an acid catalyst, such as sulfuric acid or p-toluenesulfonic acid.

CH3CHCHCOOR is a versatile intermediate in organic synthesis. It can undergo various reactions, such as reduction, oxidation, and nucleophilic addition, to yield a wide range of products. For example, reduction of the ketone group can lead to the formation of a secondary alcohol, while oxidation can result in the formation of a carboxylic acid. The ester group can also undergo hydrolysis or transesterification reactions.

The compound is used in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also a useful reagent in the preparation of other β-keto esters and related compounds. However, like many organic compounds, CH3CHCHCOOR should be handled with care due to its potential toxicity and reactivity.
