Application
Bromonitromethane has been used:
- in production of various protected α-bromo nitroalkane donors (including Fmoc) for use in Umpolung amide synthesis
- in preparation of (Z)-1-bromo-1-nitroalkenes via sodium iodide-catalyzed Henry reaction
- in diastereo- and enantioselective cyclopropanation of β,γ-unsaturated a-ketoesters via domino Michael-addition/intramolecular-alkylation strategy

A novel methodology has been developed to obtain enantiopure 2-C-glycosyl-3-nitrochromenes. First, (Z)-1-bromo-1-nitroalkenes were prepared from the corresponding sugar aldehydes through a sodium iodide-catalyzed Henry reaction with bromonitromethane followed by elimination of the resulting 1-bromo-1-nitroalkan-2-ols. In the next step, reaction of

A highly diastereo- and enantioselective cyclopropanation of β,γ-unsaturated α-ketoesters with bromonitromethane has been successfully developed through a domino Michael-addition/intramolecular-alkylation strategy. Acceptable yields (up to 89%) and enantioselectivities (up to 96% ee) have been obtained.

This study investigated the degradation of eight aliphatic halogenated contaminants (one brominated flame retardant and seven disinfection by-products) in synthetic drinking water by the UVA/TiO2 and UVA/Cu-TiO2 processes. The degradation rate constants of 2,2-bis(bromomethyl)-1,3-propanediol and trichloromethane in the UVA/Cu-TiO2 process
