Conclusions
-
1.
The formation of neutral and anion-radical particles was shown during the photoreduction of adducts of dichlorocarbene with 3,6-di-tert-butyl-o-benzoquinone in inert media and in the presence of amines, respectively.
-
2.
The presence of thermo- and photoisomerization was shown for two forms of a neutral radical formed during the photoreduction of an adduct of 3,6-di-tert-butyl-o-benzoquinone with two dichlorocarbene fragments, consisting in opening of a three-membered ring with the formation of α,α′-dichloroalkyl radicals.
