Transmetallation of β-allenyl silanes: efficient synthesis of dienyl chlorostannanes and chlorostibinesElectronic supplementary information (ESI) available: NMR spectra of compounds 1a and 2a. See http://www.rsc.org/suppdata/cc/b1/b111580b/
The reaction of 1-trimethylsilylbuta-2,3-diene with tin tetrachloride, antimonytrichloride or antimonypentachloride gave the corresponding buta-1,3-dien-2-yl halostannane or stibine derivatives; this ligand exchange was extended to other beta-allenylsilanes.

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.
