Conclusions
A study was made of the diene condensation of hexachlorocyclopentadiene with trimethylsilyldiacetylene, pentamethyl(ethynyl)-1,2-disilylethylene, and pentamethyl(ethynyl)-1,2-disilylacetylene, and also with pentamethyl(ethynyl)disiloxane. The presence of a silicon atom between the multiple bonds sharply lowers the reactivity of the studied dienophiles.
