Di-tert-butoxyacetylene

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.^[1]
