DEFINITION

Classification: 558/243

(under subclass 230) Compounds which have the thiocarboxylate group as part of an -X-C(=X)X- group, wherein the X's are the same or diverse chalcogens, (i.e., oxygen, sulfur, selenium, or tellurium), at least one of the X's is sulfur, and one of the single bonded X's is bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon.
