Abstract
The behaviour of some 2/-phenyl-4R-2,4'-bisthiazoles with respect to e lectrophilic substitution reactions (halogenation and nitration) has b een studied in order to establish relationships between structure and reactivity of the two thiazole rings. The entry of the electrophilic r eactants in position 5 or 5' of the 2,4'-bisthiazole system depends on the nature of the residue in position 4.
