2,3′-Biquinolyl dianion reacts with organolithium and organomagnesium compounds with the formation, after treatment of the reaction mixture with water, of 2′-alkyl(aryl)-1′,2′-dihydro-2,3′-biquinolyls, and, after treatment of the reaction mixture with alkyl halides, of 1′-alkyl-2′-alkyl(aryl)- 1′,2′-dihydro-2,3′-biquinolyls. The reaction includes attack of the nucleophilic reagent with an electron transfer to a molecule of solvent.
Investigation of 2,3′-biquinolyl. 10. The regioselectivity of the reaction of 2,3′-biquinolyl and 1′-alkyl-3-(2-quinolyl)quinolinium halides with halo derivatives in the presence of metallic lithium and magnesium

2,3′-Biquinolyl reacts with halo derivatives in the presence of metallic lithium to give addition products at position 4′, treatment of which with water gives 4′-R-1′,4′-dihydro-2,3′-biquinolyls and with halo derivatives gives 1′-alkyl-4′-R-1′,4′-dihydro-2,3′-biquinolyls. The reaction of 2,3′-biquinolyl with halo derivatives in the presence of metallic magnesium gives a mixture of products of addition at positions 2′ and 4′. 1-Alkyl-3-(2-quinolyl)quinolinium halides and halo derivatives with metallic magnesium give 1′-alkyl-2′-R-1′,2′-dihydro-2,3′-biquinolyls but form a complex mixture of substances when metallic lithium is used.
