Di-''tert''-butoxyacetylene is the

organic compound In chemistry, organic compounds are generally any chemical compounds that contain carbon- hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Th ...

with the formula (CH₃)₃COC≡COC(CH₃)₃. A pale yellow liquid, it is one of the more common dialkoxyacetylenes. Most other dialkoxyacetylenes are very labile. For example, dimethoxyacetylene polymerizes within seconds at 0 °C. Di-''tert''-butoxyacetylene can be prepared from

1,4-dioxane 1,4-Dioxane () is a heterocyclic organic compound, classified as an ether. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether. The compound is often called simply dioxane because the other dioxane isomers ( 1,2 ...
