Over the past decade, a few novel silylenoids have been the subject of the extensive study. Silylenoid (R2SiMX) is a species which has an electropositive metal (M, alkali metal) and a leaving group (X, usually halogen) bound to the same silicon atom. Recently, we reported halosilylenoids, which were stable at room temperature. Bromosilylenoid 1, having the bulky substituent, Tsi (= trisyl, tris(trimethylsilyl)methyl group), was synthesized by the reduction of tribromotrisylsilane with 2 equivalent of LiNp (lithium naphtalenide). Using the bromosilylenoid, 1, we have studied its reactivity with various carbonyl, such as dimethylpentanone, adamantanone, cyclohexanone, and dimethylcyclohexanone. In the reaction of 1 with cyclohexanone, after an excess amount of cyclohexanone were added to bromosilylenoid, 1, the treatment of the reaction mixture with an excess of H2O, MeOH and i-PrOH gave the corresponding products. In this presentation, we will discuss reactivities of bromosilylenoid with ketones in detail.
