Heterocyclic Compounds with Two or More Ring-Chalcogen Atoms 4

Voume 19 of the 5th Supplementary Series of the Beilstein Handbook (4th Edition) deals with the heterocyclic compounds containing two or more chalcogen atoms as the only ring heteroatoms, which were reported in the literature from 1960 up to 1980. Subvolume 19/4 continues the coverage of heterocycles containing two chalcogen atoms (heterocyclic class: 2O) and deals with monoxo-compounds (CnH2n-2O3 to CnH2n-56O3).
