    • The reactivities of internal alkynes were much lower than those of the terminal alkynes. For example, the allylsilylation of 1-phenyl-1-propyne afforded less than 10% yield of product for 24 h.

    • The selectivity of silylated alkyne (5) based on the alkyne (1) used was high. However, the formation of silylated ether solvent, such as 1,2-bis(trimethylsiloxy)ethane, was also detected.
