Synthesis

1,1-Dibromoethane is synthesized through addition of hydrogen bromide onto vinyl bromide with absence of peroxide radical.[6]

Safety

1,1-Dibromoethane is considered as a mild toxic compound, especially with bromines attached as substituents. Bromines on the ethane are strong oxidizing agents. If absorbed through inhalation, 1,1-dibromoethane could potentially cause neuronal effects, tissue damage, and bromism.[7]
