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

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.

CHEMISTRY OF DIENES AND THEIR DERIVATIVES. XVII. LOW-TEMPERATURE CHLORINATION OF 2-CHLORO- AND 1,2-DICHLORO-1,3-BUTADIENES IN THE PRESENCE OF AN INHIBITOR OF RADICAL REACTIONS

During the chlorination of chloroprene (80-85percent conversion) in carbon tetrachloride at -5 to 0 deg C in the presence of tert-butylpyrocatechol 1,2-dichloro-1,3-butadiene, 3,3,4-trichloro-1-butene, 2,3,4-trichloro-1-butene, and 1,2,4-trichloro-2-butene are formed in percentage ratios of 20.4:6.7:3.4:69.5.During chlorination to total conversion of chloroprene under these conditions a series of other compounds are also formed as a result of the further chlorination of 1,2-dichloro-1,3-butadiene and 3,3,4-trichloro-1-butene.During the chlorination of 1,2-dichloro-1,3-butadiene to a high degree of conversion 1,2,4-trichloro-1,3-butadiene, 1,2,3,4-tetrachloro-1-butene, and 1,1,2,4-tetrachloro-2-butene are formed in ratios of 11.4:49:39.6.

INVESTIGATION IN THE FIELD OF UNSATURATED COMPOUNDS. V. ANOMALOUS CHLORINATION OF ETHYLENE COMPOUNDS CONTAINING A CHLORINE ATOM AT THE DOUBLE BOND

The liquid-phase chlorination of isomeric dichlorobutenes in a nonpolar medium was investigated in the presence of tert-butylpyrocatechol and without additions.The addition of tert-butylpyrocatechol leads to an increase in the yield of the products from anomalous chlorination and to a decrease in the yield of the products from normal addition.Increase in temperature during the chlorination of dichlorobutenes in the absence of tert-butylpyrocatechol promotes the formation of the normal addition products.It was suggested that the anomalous reaction, which leads to chlorides of the allyl and vinyl types, takes place by a molecular mechanism while the normal addition reaction takes place by both mechanism (molecular and radical).
