摘要：

The macrocyclic cyano crown formazans 3a-c and cyano crown formazans with two formazyl moieties 4a-c were prepared by the azo coupling of the appropriate bis diazonium salts 2a-c with cyanoacetic acid in different medium. The Bis macrocyclic crown formazan 9 was prepared by condensation of 1.3-diaminopropane with the 16-oxo crown formazan 8. The latter was prepared by ozonolysis of 16-methylene crown formazan 3a.
