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

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

David R Geter et al.

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

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
