Abstract
A method for production of novel antifungal 1,3,4-thiadiazole derivatives having a composition of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are independently alkyl with from 1 to 6 carbon atoms, alkenyl with from 2 to 6 carbon atoms, alkinyl with from 2 to 6 carbon atoms or cycloalkyl with from 3 to 6 carbon atoms is provided. 1,3,4-thiadiazole derivatives of a composition of the general formula ##STR2## are reacted with a compound having the composition of the general formula R.sub.1 -SH resulting in compounds of a composition having the formula ##STR3## which in turn are oxidized with an organic or inorganic oxidant.
