Abstract
The reaction between dichlorosilanes and conjugated dienes is closely dependent upon the metal and the solvent. New 1-silacyclopent-3-enes, with various substituents at the heteroatom, are prepared in good yield with Mg, THF and butadiene. For isoprene and dimethylbutadiene, a THF-HMPT mixture must be generally used to increase the ring closure reaction and to limit the competitive reaction of polymerisation to a low value.Keywords
