Reactions of quinones with organometallic compounds: correlation analysis of substituent effects

详细

The effects of substituents in lithium, magnesium, zinc, and cadmium organometallic compounds in their reactions with p-benzoquinone and 3,6-di-tert-butyl-o-benzoquinone on the ratio of addition and reduction products were considered. The reduction of quinones follows a homolytic mechanism of single electron transfer. The results of correlation analysis confirmed a suggestion that the addition to quinones followed a nucleophilic (heterolytic) mechanism.
