Vf. Anikin et al., Alkylation of 1H-benz[de]isoquinoline-1,3(2H)dione and benz[cd]indol-2(1H)one under conditions of phase-transfer catalysis, RUS J AP CH, 73(3), 2000, pp. 486-489
The possibility of phase-transfer N-alkylation of 1H-benz[de]isoquinoline-1
,S(2H)-dione (naphthalmide) and benz[cd]indol-2(1H)-one (naphthostyril), ca
talyzed with tetraalkylammonium nitrates, was studied.
