It is prepared from acetylene and bromine in multiple steps.[1][3] One method involves dehydrobromination of pentabromoethane, other method involves bromination of dibromoethylene in chloroform.[1] Reaction of mercuric acetylide and bromine also gives tetrabromoethylene.[4] It can be produced by oxybrominating butane with free oxygen and bromine.[5]

Tetrabromoethylene gives tribromoacetyl bromide upon treatment with fuming nitric acid.[6]
