Hello Stephanie.

Something to start with:

J. Zabicky, The chemistry of bromination of wood. IV. Main features
of the reaction of Picea Exelsa with aqueous bromine at low pH and low =

bromine concentrations. Holzforschung, 24, 158 (1970)

J. Zabicky, The chemistry of bromination of wood, V. Main features of =

the reaction of Picea Exelsa with aqueous bromine at low pH and high
initial bromine concentrations. Holzforschung, 25, 89 (1971)

J. Zabicky and M. Nutkovitch, Reactions of bromine and cyclohexene in
aqueous media. Selectivity of bromohydrin vs. dibromo adduct
formation. Ind. Chem. Eng. Prod. Res. Dev., 25, 372 (1986).

These things were done when green chemistry was not yet in the public
interest, but that can be revived.

Good luck,

Jacob
