The Wurtz-Fittig coupling reaction of 2,3-dichloronorbornene (1) with sodium and chlorotrimethylsilane in anhydrous THF solvent is reported. The novel reaction affords 2,3-bis(trimethylsilyl)norbornene (2), along with a small amount of reductive carbon-carbon ring cleaved product (3'-trimethylsilylcyclopentanyl)-l-trimethylsilylacetylene (3).
