Thiolation of 3-nitro-4-chlorocoumarin in the presence of a substituted or unsubstituted ammonium ion can be used to isolate 3-nitro-4-coumarinylthiolates, which are stabilized by the corresponding ammonium cation, while 3-nitro-4-mercaptocoumarin or its

3-Nitro-4-chlorocoumarin forms 3-nitro-4-substituted coumarins when it reacts with an equimolar quantity of benzyl mercaptan or thiosalicylic acid; with excess benzyl mercaptan, it forms 3,4-di-S-benzyl coumarin. 3-Nitro-4-methoxycoumarin under the same c
