Descrição geral

Bromoform (CHBr3), also known as Tribromomethane, is a very short-lived substance (VSLS) and an important precursor of reactive bromine species (BrOx). It is widely used as a laboratory reagent and as an industrial extraction solvent. It can also be used as a sedative and to create block copolymers.

Aplicação

Bromoform (Tribromomethane) was used in the synthesis of α-tribromomethylated N-sulfonylamines.

Mg-mediated addition of bromoform to electron deficient imines such as N-sulfonylimines affords α-tribromomethylated N-sulfonylamines in good to excellent yields. The procedure could be further simplified by transforming the imine precursors, α-sulfonyl-N-tosyl- and Boc-amines, in one pot to the corresponding α-tribromomethyl
