ChemInform Abstract: UV/VIS Absorption Spectra of Azo Dyes. Part 24. The Different Effect of a 2‐Methoxy and a 3‐Methoxy Group in 4‐N,N‐Diethylaminoazobenzenes on Color.

Abstract

ChemInform Abstract Both the 2-and 3-methoxy groups in (II) and (III) cause a bathochromic shift as compared to the corresponding (I), but the bathochromic shift of a 3-methoxy group in (III) depends on the substituents in the diazo component.
