Hello Jon,

Two good replacements are worth trying, limited of course by the nature =

of the bromination substrate and the budget you have at hand for
development of alternative technology:

1. Bromination in the gas phase.

2. Bromination in water.

The solvent is in both cases far cheaper and more environmentally
friendly than CCl4. The results may be surprising!

Have a nice day/week/month/year/lifetime (*)

Jacob
