Reactions

Dimethyl 4,4'-(ethyne-1,2-diyl)dibenzoate

The aryl-iodide functionality of methyl 4-iodobenzoate may undergo coupling reactions, such as a symmetrical Sonogashira coupling with trimethylsilylacetylene (with the TMSA deprotected to acetylene in situ) to form dimethyl 4,4'-(ethyne-1,2-diyl)dibenzoate.^[4][5]
