What is Reaktionen mit N‐Acylimino‐dithiokohlensäurediestern about?

**Reactions with N‐Acylimino‐dithiocarbonic‐acid‐diesters**. Reactions of N‐acylimino‐dithiocarbonic‐acid‐S,S‐diesters 1 with nucleophilic com‐pounds present new possibilities to synthesize heterocycles. With amines **1a** reacts by mono‐ and disubstitution, respectively, of methylthio‐groups to isothioureas **2** and guanidines **3**, with 1,2‐bi‐nucleophilic arenes to benzoheterocycles **4**, with aliphatic diamines to imidazolidines **5**, pyrimidines **6**, diazepines **7** and the hexamethylene‐diamine‐derivatives **8. 1a** reacts also with hydrazines to 1,2,4‐triazoles **9** and with hydrazides to the thiosemicarbazones **10** or 1,3,4‐oxadiazoles **11**. Heterocyclisations of **1** with guanidines, thiourea, salts of thiourea and amidines give the 1,3,5‐triazines **12, 14, 15** and **16**. N‐benzoyl‐dithiocarbonic‐acid‐methylester ‐amid reacts with CH‐acidic compounds to thiazoles **17**. The structures of the final products are determined by i.r.‐, ^1^H‐n.m.r.‐, u.v.‐ and mass‐spectras.
