Transmetallation of beta-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 beta-allenylsilanes.
