To date, 1-trimethylsiloxy-1,2-propadiene (10) has been described only as a product of the high-temperature retro-Diels-Alder reaction of an anthracene adduct performed on a very small scale: A. Hakiki, J.-L. Ripoll, A. Thuillier, Bull. Soc. Chim. Fr. 1985, 911-920.

Lithiation of 2,2-dimethyl-4-methylene-[1,3]dioxolane with commercially available 2.5 M nBuLi gave a higher yield and purity of 10 than with 1.3 M sBuLi (both from Aldrich).
