Synthesis of 3-Alkyl/Aryl-3-Triocyanatoquinoline-2,4(1H,3H)-Diones and their Reactions with Nucleophiles
Original language description
The preparation of title compounds is decribed by reaction of corresponding 4-hydroxy-2-quinolones with thiocyanogen. The prepared thiocyanato derivatives are very reactive and smoothly hydrolyse to starting 4-hydroxy-2-quinolones. Their reactions with nucleophiles proceed always at sulfur atom and, therefore, they act as thiocyanation agents. By the reaction with aliphatic amines, S-cyanothiohydroxylamines arise, aromatic amines are thiocyanated in nucleus, Wittig reagents are thiocyanated in alfa-position and compounds bearing -SH group are oxidized to disulfides.
