Established in 1960, Advances in Heterocyclic Chemistry is the definitive serial in the area--one of great importance to organic chemists, polymer chemists, and many biological scientists. Every fifth volume ofAdvances in Heterocyclic Chemistry contains a cumulative subject index. Key Features * A selection of topics covered in Volume 62 * Synthesis possibilities in N-Fluoropyridinium salts * An updated review of Pyran Chemistry * The organic chemistry and synthesis of Tetrathia- and tetraselena-fulvalenes * A review of the classes of five-membered heterocyclic rings containing two sulfur and two nitrogen atoms, both as anionic and radical species.
