Tetrabromoethylene is a brominated derivative of ethylene. Tetrabromoethylene is a potential fungicide and bactericide on fruits. [1] It was used in mineral separation. [2]
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]
