Tetrabromoethylene Explained

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

It is prepared from acetylene and bromine in multiple steps.^[2] One method involves dehydrobromination of pentabromoethane, other method involves bromination of dibromoethylene in chloroform.^[3] 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]
