摘要
Conjugative effects are not significant for the conformation of diaryl‐substituted azines such as 1—whether within the azine unit or between the aryl substituents and the azine or imino units. This was the conclusion of studies of X‐ray crystal structures and quantum chemical calculations. (Figure Presented.) Copyright © 1994 by VCH Verlagsgesellschaft mbH, Germany
