Synthesis and epoxidation of 1,3-, 1,4-, and 1,5-alkadienes with pentafluoro-λ6-sulfanyl (SF5) groups

This paper describes a convenient and efficient synthesis of new pentafluoro-λ6-sulfanyl-containing 1,3-, 1,4- and 1,5-alkadienes and their epoxidation. These compounds are useful as monomers or as intermediates in the preparation of polymers, polymer surface coating and SF5-containing heterocyclic compounds. Georg Thieme Verlag Stuttgart.

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.

Halogen Epoxides, 4. Synthesis, Stability and Reactions of 2-Chloro-2-(1-chloroalkyl)oxiranes with AgBF4

Reactions of 3-chloroperbenzoic acid with 2,3-dichloro-1-butene (1a), 2,3-dichloro-3-methyl-1-butene (1b), (Z)- and (E)-1,2-dichloro-2-butene (1c, d) and with 1,2-dichloro-3-methyl-2-butene (1e) afforded the corresponding epoxides (2a - e).They rearranged slowly at room temperature and fast at elevated temperatures to form the corresponding isomeric α,α'-dichloroketones (3a, b).Reactions of the epoxides with AgBF4 produced α-chloro-α'-fluoroketones.
