Heterocyclic Selenium- and Tellurium-Nitrogen Compounds

Autor: Daniel D. Doxsee, Tristram Chivers

Publikováno v: Comments on Inorganic Chemistry. 15:109-135

The methods available for the synthesis of selenium-nitrogen (Se-N) heterocycles are discussed. The chemistry of phosphorus-containing Se-N and Te-N ring systems is described and compared with that of the corresponding S-N heterocycles. The P2N4Se2 r
