Conclusions
-
1.
The reaction of 3,6-di-tert-butyl-1,2-benzoquinone with the halides of the Group III elements leads to paramagnetic chelate complexes.
-
2.
A simple method was proposed for determining the relative stability of the chelate bond in the halide complexes of o-semiquinones, and the order of their stability in THF is given.
