- -quinones. A study of their monoreduced semiquinone derivatives reveal that the spin density is delocalized across the whole molecule, including peripheral fragments. The first stable o-quinone derivative bearing an annulated thiete heterocycle has been isolated and characterized. Keywords: dioxolene
- ligand; 1,3-dithiole; ditopic ligand; o-quinone; thiete; Introduction There are a number of methods which may be used for the synthesis of new o-quinones in order to vary their redox properties and coordination abilities. The key features of o-quinones are redox activity as well as chelating
- was not the only product of the reaction of 4 with acetylacetone gem-dithiolate 5d. The final mixture also contained o-quinone 7 with attached four-membered thiete ring (Scheme 1 and Scheme 2). The formation of the latter was surprising for us. The X-ray study of 6d revealed that the six-membered o
