1,3-bis(trimethylsilyl)-1-alkynes may be obtained from trimethylsilylpropargylsilanes by metallation with n-butyllithium following by reaction with trimethylsilylchloride ; these silanes easily react with acetals, in presence of titanium tetrachloride, to produce α-functional allenyltrimethylsilanes.
