The 4,3-addition product is formed preferentially together with the 4,1-, 1,4-, and 1,2-addition products during the hydrochlorination of α-chloroisoprene (1-chloro-3-methyl-1,3-butadiene) with concentrated hydrochloric acid at room temperature with and without the presence of cuprous chloride.During low-temperature (-15 deg C) chlorination of a mixture of 1,3-dichloro-3-methyl-1-butene and 1,1-dichloro-3-methyl-2-butene in the presence of tert-butylpyrocatechol the anomalous chlorination product 3,4,4-trichloro-2-methyl-1-butene is mainly formed. 1,3-Dichloro-3-methyl-1-butene is not chlorinated under these conditions.
