PROCESS FOR PRODUCTION OF 2,3-DICHLOROBUTADIENE-1,3

2,3-dichlorobutadiene-1,3 of high purity is produced from 1,2,3,4-tetrachlorobutane by a process comprising the steps of dehydrochlorination, chlorination of the reaction product obtained in the dehydrochlorination step and subsequent separation of a 2,3-dichlorobutadiene-1,3 composition from the reaction product of the chlorination step.

Transmetallation of β-allenyl silanes: Efficient synthesis of dienyl chlorostannanes and chlorostibines

The reaction of 1-trimethylsilylbuta-2,3-diene with tin tetrachloride, antimony trichloride or antimony pentachloride gave the corresponding buta-1,3-dien-2-yl halostannane or stibine derivatives; this ligand exchange was extended to other β-allenylsilane

INVESTIGATIONS IN THE FIELD OF UNSATURATED COMPOUNDS. XIII. ANOMALOUS CHLORINATION OF 1,2,4-TRICHLORO-2-BUTENE IN THE PRESENCE OF FERRIC CHLORIDE

It was shown that the low-temperature (-5 to 25 deg C) chlorination of 1,2,4-trichloro-3-butene with chlorine in the presence of anhydrous ferric chloride and tert-butylpyrocatechol leads to the formation of an anomalous reaction product and an addition product .It was found that the composition of the products from the chlorination of 2,3,4-trichloro-1-butene is close to the composition of the products from the reaction of 1,2,4-trichloro-2-butene with chlorine.
