Di-tert-butoxyacetylene is the organic compound with the formula (CH3)3COC≡COC(CH3)3.
It is 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 in a multistep procedure.
