α,α-Disilylenolates generated in situ from disilylketenes and organolithiums in the presence of HMPA undergo the Peterson-type elimination to give silylacetylene derivatives in moderate to good yields. Geminal disilyl substitution on ketene moiety is crucially important for the successful elimination from the corresponding α,α-disilylenolates.
