Cyclopropanecarbonyl chloride, 2,2-dimethyl-

Description:

Cyclopropanecarbonyl chloride, 2,2-dimethyl- is an organic compound characterized by its unique cyclopropane ring structure and the presence of a carbonyl chloride functional group. This compound features a cyclopropane moiety, which contributes to its strain and reactivity, making it an interesting subject in synthetic organic chemistry. The presence of the carbonyl chloride group indicates that it can participate in nucleophilic acyl substitution reactions, making it useful in the synthesis of various derivatives. The 2,2-dimethyl substituents enhance steric hindrance, influencing its reactivity and interaction with other molecules. Typically, compounds like this are colorless to pale yellow liquids and may have a pungent odor due to the presence of the acyl chloride functional group. Safety precautions are essential when handling this compound, as it can be corrosive and may release harmful gases upon hydrolysis. Overall, cyclopropanecarbonyl chloride, 2,2-dimethyl- is a valuable intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals.

2,2-Dimethylcyclopropane-1-carbonyl chloride

CAS: 50675-57-5

2,2-Dimethylcyclopropane-1-carbonyl chloride is a diastereomeric mixture of two diastereoisomers. It is soluble in chloroform and diethyl ether and crystallizes from acetone. 2,2-Dimethylcyclopropane-1-carbonyl chloride is used as a feedstock to produce cyhalothrin, an insecticide that acts by contact. The insecticide is made by esterification of the 2,2-dimethylcyclopropane-1-carbonyl chloride with 3-phenoxybenzaldehyde and then chlorination of the ester.
A mixture of two diastereoisomers can be separated using chromatography techniques such as gas chromatography or high performance liquid chromatography (HPLC). In this case it would be possible to use HPLC to separate the two diastereoisomers.
