title: [A study on the ultraviolet spectra of halogenated benzoylferrocenes].
abstract: The ultraviolet spectra of all of the o, m, p-halogenated benzoylferrocenes have been studied the following rules obtained: 1. The lambdamax of the ultraviolet spectrum R band and K band for the isomers is lambdamax(m-X) > lambdamax(p-X) > lambdamax(o-X). 2. With the same substituted positions of the different halogen on the benzene ring, the lambdamax of the ultraviolet spectrum K band is lambdamax(C1) > lambdamax(Br) > lambdamax(I) > lambdamax(F), then, the lambdamax of ultraviolet spectrum R band is lambdamax(I) > lambdamax(Br) > lambdamax(Cl) > lambdamax(F).
