UNSATURATED COMPOUNDS. XV. LIQUID-PHASE LOW-TEMPERATURE CHLORINATION OF 2-CHLORO- AND 2,3-DICHLORO-2-BUTENES IN THE PRESENCE OF FERRIC CHLORIDE

The effect of anhydrous ferric chloride on the degree of normal and anomalous chlorination of 2-chloro- and 2,3-dichloro-2-butenes at low temperatures (-20 to 0 deg C) in the presence of tert-butyl pyrocatechol was investigated.It was established that the addition of ferric chloride leads to a significant decrease in the amount of anomalous chlorination products.At the same time an increase is observed in the chlorination rate of trans-2,3-dichloro-2-butene. During the chlorination of 2,3-dichloro-2-butene under the influence of ferric chloride the anomalous chlorination product 2,3,3-trichloro-1-butene isomerizes to 1,2,3-trichloro-2-butene.

INVESTIGATION IN THE FIELD OF UNSATURATED COMPOUNDS VI. LIQUID-PHASE CHLORINATION OF 2-HALOGENO-2-BUTENES

The liquid-phase chlorination of 2-halogeno-2-butenes in the presence of tert-butylpyrocatechol leads to the formation of the products from an anomalous reaction (2,3-dihalogeno-1-butenes), substitution of hydrogen at the double bond (2,3-dihalogeno-2-butenes), and normal addition (2,2,3-trihalogenobutanes).The ratios of these compounds are 70:6:24 in the case of 2-chloro-2-butene and 54:7.5:38.5 in the case of 2-bromo-2-butene.During the chlorination of 2-chloro-2-butene in the presence of sodium bicarbonate the formation of 3-chloro-2-butanol (20percent) was observed as a result of the combined addition of chlorine and water.
