Abstract:

Unsymmetrical 2,3-dimethyl-5-silaspiro4,4nona-2,7-diene I has been prepared by a dissolving metal reaction between 1,1-dichloro-1- silacyclopent-3-ene III and 2,3-dimethyl-1,3-butadiene. Ring opening reactions of I catalyzed by alkyllithium reagents and hexamethylphosphoramide HMPA have been explored. Keywords Dimerization of 2,3-dimethyl-5-silaspiro4.4nona-2,7- diene, 5,10-Disiladispiro4,4,4,4octadeca-2,7,12,16-tetraene, Structure by x-ray crystallography, Organometallic compounds, Composite materials.
