| 230 | DF | .~ Esters having the thiocarboxylate group, -C(=X)X-, wherein the X's are the same or diverse chalcogens, with at least one X being sulfur, and wherein the single bonded X is bonded directly to an additional carbon, which carbon may be single bonded to any atom, but may be multiple bonded only to carbon {5} |
| 243 | DF | .~.~ Esters having the -X-C(=X)X- group, wherein the X's are the same or diverse chalcogens and at least one X is sulfur, and wherein 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 (e.g., thiocarbonates, etc.) {3} |
| 245 |  | .~.~.~ The -X-C(=X)X- is -S-C(=S)O- (e.g., xanthates, etc.) {2} |
| 246 | DF | .~.~.~.~> Nitrogen or chalcogen attached indirectly to the -S-C(=S)O- group by acyclic nonionic bonding |
| 247 | DF | .~.~.~.~> Alkyl and hydrogen bonded directly to the -S-C(=S)O- group, wherein the hydrogen may be replaced by substituted or unsubstituted ammonium or by a Group IA or IIA light metal (e.g., sodium ethyl xanthate, etc.) |
