Procedure

This material was synthesized by methods identical to those used to prepare allyldiisopropylsilyl acetylene (Example 1), simply substituting 2-lithio-1-butene (generated in situ by treating 2-bromo-1-butene with n-BuLi in tetrahydrofuran at −78° C.) for allyl magnesium bromide. 1H-NMR (200 MHz, CDCl3) δ=5.76 (q, J=1.2 Hz, 1H), 5.55 (quint, J=1.2 Hz, 1H), 2.41 (s, 1H), 1.06 (br. s, 14H), 2.19 (q, t, J=9.5, 1.2 Hz, 2H), 1.10 (t, J=9 Hz, 3H).
