Reaction of the bis-9-BBN adduct of several dienes with 1,3-dibromobenzene via Suzuki coupling leads to a series of [n]metacyclophanes ranging in size from 10 to 17 atom members. In each case, two carbon-carbon bonds are formed in one reaction vessel.

The distribution, excretion and metabolism of 1,3-dibromobenzene following a single i.p. administration to rats 100 or 300 mg/kg was investigated using radiotracer [3H] and GC-MS technique. After 72 hours about 74 to 90% were excreted in urine. The highest radioactivity

Rats were used to study acute and subacute hepatotoxicity of 1,3-dibromobenzene (1,3-dBB). In the single-exposure experiment, maximum hepatic 1,3-dBB concentrations were found to occur 1 to 12 h after the exposure, depending on the dose. Maximum concentrations of covalently bound
