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.
Investigations in the region of 2,3′-biquinolyl. 4. Alkylation of the dianion of 2,3′-biquinolyl

, p. 1041 - 1044 (1998)
With alkyl chlorides and alkylphenyl ethers the dianion of 2,3′-biquinolyl forms the products from alkylation at position 4′. Their treatment with alkyl halides or water gives 1′,4′-dialkyl-1′,4′-dihydro-2,3′-biquinolyls or 4′-alkyl-1′,4′-dihydro-2,3′-biquinolyls respectively. 1999 Kluwer Academic/Plenum Publishers.
Studies of 2,3′-biquinolyl. 6. Regioselectivity of nucleophilic addition of organometallic compounds to 1-aklyl-3-(2-quinolyl)quinolinium halides

, p. 804 - 808 (2007/10/03)
Nucleophilic addition of organometallic lithium and magnesium compounds to 1-alkyl-3-(2-quinolyl)quinolinium cations produces a mixture of the corresponding 1′-alkyl-2′-R-1′,2′-dihydro-2,3′-biquinolyls and 1′-alkyl-4′-R-1′,4′-dihydro-2,3′-biquinolyls. The
