2-Trimethylsilyl-1,3,3-trimethylcyclopentene and 2-trimethylsilyl-1,3,3-trimethylcyclohexene were prepared in good yields by the Wurtz-Fittig coupling reaction of the corresponding 2-iodo-1,3,3-trimethylcyclopentene and 2-chloro-1,3,3-trimethylcyclohexene with metallic sodium and chlorotrimethylsilane in anhydrous ether solvent. The Friedel-Crafts acylation reaction of 2-trimethylsilyl-1,3,3-trimethylcyclopentene with six different acid chlorides and the novel preparation of six alkyl/alkenyl/aryl-(1?,3?,3?-trimethylcyclopentenyl)ketones is reported.
