A bioinspired two-component redox organocatalyst system using 1,10-bridged flavinium and NH4I was developed to perform environmentally friendly aerobic oxidative ring formation of 1,2,3-thiadiazoles from N-tosylhydrazones and sulfur. The redox organocatalysis of the flavinium promoted the iodine-catalyzed system without the use of any sacrificial reagents, except for environmentally benign molecular
Transition-metal heterocyclic chemistry. 10. A dimeric selenoketoketene complex and doubly reduced thioketohydrazonato complexes from reactions of 1,2,3-selena- and 1,2,3-thiadiazoles with diiron enneacarbonyl in the presence of alcohol
