Application

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

General description

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.

Synthesis of α-tribromomethylamines via Mg-mediated addition of bromoform to imines.

Elumalai Gopi et al.

Organic & biomolecular chemistry, 12(17), 2769-2777 (2014-03-29)

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

Ultrafast observation of isomerization and complexation in the photolysis of bromoform in solution.

Stacey L Carrier et al.

The journal of physical chemistry. A, 114(3), 1548-1555 (2009-12-09)

Ultrafast photolysis of bromoform (CHBr(3)) with a 267 nm pulse of light followed by broadband transient electronic absorption identifies the photoproducts and follows their evolution in both neat bromoform and cyclohexane solutions. In neat bromoform, a species absorbing at 390

Global sampling of the photochemical reaction paths of bromoform by ultrafast deep-UV through near-IR transient absorption and ab initio multiconfigurational calculations.

S K Pal et al.

The Journal of chemical physics, 138(12), 124501-124501 (2013-04-06)

Ultrafast deep-ultraviolet through near infrared (210-950 nm) transient absorption spectroscopy complemented by ab initio multiconfigurational calculations offers a global description of the photochemical reaction pathways of bromoform following 255-nm excitation in methylcyclohexane and acetonitrile solutions. Photoexcitation of CHBr3 leads to

Tribromomethane exposure and dietary folate deficiency in the formation of aberrant crypt foci in the colons of F344/N rats.

Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 43(9), 1405-1412 (2005-06-01)

Folate and folic acid are forms of the B vitamin that are involved in the synthesis, repair, and functioning of DNA and are required for the production and maintenance of cells. Low levels of folate have been associated with several

Trihalomethanes in chlorine and bromine disinfected swimming pools: air-water distributions and human exposure.

Carolina Lourencetti et al.

Environment international, 45, 59-67 (2012-05-11)

This first study of trihalomethanes (THMs) in swimming pools using bromine agents for water disinfection under real conditions shows that the mixtures of these compounds are largely dominated by bromoform in a similar process as chloroform becomes the dominant THM
