摘要：

1,2-Diaminobenzene dianion (1) can be oxidized to 1,2-benzosemiquinone diimine monoanion (2) and to 1,2-benzoquinone diimine (3). The known structural parameters of 28 ligands of formula 1-3 (the charge is disregarded) are analyzed by multivariate methods (principal component analysis). It is found that: (i) the greatest part of the variance is related to the oxidation state of the ligands; (ii) there are two reaction pathways from 1 to 3, only one conserving the C-2v symmetry; (iii) the factor determining which path is followed depends on the hydrogen bonds between the NH functions and sur rounding hydrogen acceptor molecules.
