The effect of changing the solvent from a hydrocarbon to acetonitrile on the mechanism of the addition of aldehydes to a disilene and two silenes was investigated. The products of the reaction between Mes2Si═CH(CH2-t-Bu) and acetonitrile were characterized.

A variety of alkyllithium (R = Me, Bu, t-Bu) reagents and potassium tert-butoxide were added to the highly reactive silene Mes(2)Si=CHCH(2)t-Bu (1) and the germene Mes(2)Ge=CHCH(2)t-Bu (4) in diethyl ether. 1,2-Addition products were obtained regioselectively and in good yield after treatment with a weak acid with no evidence for any rearrangement products and no polymerization observed. The reactivity of the silene 1 and germene 4 toward organometallic reagents is compared to previous studies of analogous silenes and germenes.

The simple synthesis in nearly quantitative yield of dimesityl-neopentylsilene 3, the first stable silene in the neopentyl series, was performed using t-butyllithium and dimesitylvinylfluorosilane. 3 was isolated by crystallization from pentane and characterized by C-13 (doubly bonded carbon at + 110.4 ppm) and Si-29 (+ 77.6 ppm) NMR spectroscopy and analysis.
