Oxidation of thiourea and substituted thioureas: a review

“…Oxidative degradation of ETU, the most noxious and carcinogenic metabolite of the widely used ethylene bisdithiocarbamate fungicides, has been intensively studied (109,110). This is usually degraded by using oxidants such as potassium permanganate (111), sodium hypochlorite (55), or hydrogen peroxide (49). However, the oxidants either contain heavy metals or halogen atoms leading to unwanted byproducts.…”
