The colour of benzaurine and of its alkylsubstituted derivates. Part 6: Benzeines
Kallmayer,Lenze
, p. 827 - 831 (2007/10/03)
The colour of oxonoles 5a, 6 and 7 in neutral, in alkaline and in acidic solution correlates with the π-system extension. A correlation with the symmetry of the mesomeric charge distribution is not given. The colour of benzaurines 3, 4 and 5b-j depends on the position of the alkyl substituents.
