A Cu(I)-catalyzed cross-coupling reaction of terminal alkynes and bis(trimethylsilyl)diazomethane is reported. Mechanistically, the reaction is based on the recently developed cross-coupling reactions through metal-carbene migratory insertion. This reaction provides an efficient synthetic method for 1,1-disilyl allenes. Subsequent transformations of 1,1-disilyl allenes are investigated, which show diverse reactivities of these allenes.

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.
