1,4-Dichloro-2-butyne

Description:

1,4-Dichloro-2-butyne is an organic compound characterized by its alkyne structure, featuring a triple bond between two carbon atoms. It has the molecular formula C4H4Cl2 and is classified as a dichloroalkyne due to the presence of two chlorine atoms attached to the carbon chain. This compound typically appears as a colorless to pale yellow liquid and is known for its strong, pungent odor. It is relatively insoluble in water but soluble in organic solvents. 1,4-Dichloro-2-butyne is primarily used in organic synthesis and as an intermediate in the production of various chemicals. Its reactivity is influenced by the presence of the triple bond and the electronegative chlorine atoms, making it a useful reagent in chemical reactions. However, it is important to handle this compound with care, as it may pose health risks, including irritation to the skin and respiratory system, and it is considered hazardous to the environment. Proper safety measures should be taken when working with this substance.

1,4-Dichloro-2-butyne

CAS: 821-10-3

1,4-Dichloro-2-butyne is a colorless liquid with a sweet odor. It is used as an intermediate in organic synthesis. 1,4-Dichloro-2-butyne can be prepared by the reaction of ethylene diamine and benzyl chloride in the presence of xylenes to form the corresponding ethyl diazoacetate. The ethyl diazoacetate is then reacted with chlorosulfonic acid to produce 1,4-dichlorobutane. This compound can be converted into other compounds such as amides, ethers, and esters using ethyl diazoacetate.
