A variety of alkyllithium (R = Me, Bu, t-Bu) reagents and potassium tert-butoxide were added to the highly reactive silene Mes2Si=CHCH2t-Bu (1) and the germene Mes2Ge=CHCH2t-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. (Chemical Equation Presented).

The dimesitylneopentylsilene Mes2Si=CH-CH2tBu 1 is obtained in almost quantitative yield by reaction of tert-butyllithium with dimesitylvinylfluorosilane 4; 1 is certainly one of the most easily available stable silenes. In spite of its stability, 1 presents a high reactivity in the field of classical chemistry of organometallic alkenes such as addition or cycloaddition reactions and, in some cases, an original behaviour of ene-reagent (towards benzaldehyde) and both ene- and enophilic-reagent (towards acetophenone).
