CAS 821-10-3: 1,4-Dichloro-2-butyne

1,4-Dichlorobut-2-yne

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.
