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.
