Abstract
Conjugative interaction between a g-phenyl substituent and the vinamid inium system of a dihydrodiazepinium salt appears to be less than that observed with 5- or 7-phenyl substituents; despite this, electrophili c substitution occurs very readily in the 6-phenyl group and comment i s made on a possible mechanism.
