—— | 4-thiapentane-1-thiol 4,4-dioxide | 232944-40-0 | C4H10O2S2 | 154.254 |
Synthesis and antifungal testing of 2,4,5,7,9-pentathiadecane 9,9-dioxide has established that the absence of oxygen atoms on S2 significantly attenuates fungitoxicity in accord with our earlier proposal. Attempts to convert that compound into dysoxysulfone led to the discovery of a novel oxidative conversion of unsymmetrical γ-sulfonyl disulfides into the corresponding symmetrical γ-sulfonyl disulfides.
A series of sulfur compounds has been prepared and tested against two kinds of fungi: Aspergillus niger and Aspergillus flavus. Results on various sulfone disulfides and ester disulfides have led to the formulation of a proposed mechanism for fungicidal behaviour that permits one to anticipate which structures will be antifungal.
