Brominating benzophenone

If I was to brominate benzophenone which carbon would it attach too?
Im talking alpha bromination but will it attach to the carbon on the benzene ring connected to the carbonyl carbon or would it move one over where it's not as cramped

Dont think benzophenone can be alpha brominated b/c there is no alpha hydrogen.

If bromination happens by electrophilic aromatic substitution, u would get a mixture of products like this.

edit" Probably the bottom one since each ring is deactivated by both the bromine and carboxyl, so each ring is monobrominated. Unless the proportion of bromine in the reaction is increased, benzene and its derivatives will be brominated to the monosubstituted product. Source: vogel's practical organic chemistry

Yeah I thought it would be something like that.thanks.
