Av. Vasilyev et al., Noncovalent binding of the halogens to aromatic donors. Discrete structures of labile Br-2 complexes with benzene and toluene, CHEM COMMUN, (10), 2001, pp. 909-910
Precise molecular structures resulting from the noncovalent interaction of
Br-2 with benzene (and toluene) reveal the unusual localized bonding to spe
cific (one or two) carbon centers in prereactive complexes leading directly
to the transition states for electrophilic aromatic brominations.
