(Dialkoxyphosphinothioylthio)methyl derivatives of 5-alkyl-4,5-dihydro-1,2,4-triazin-6(1H)-ones are formed when an excess of O,O-dialkyl hydrogen phosphodithioates is used.In presence of mineral acids the triazine ring is split.Under these conditions N-ethyl-5-alkyl-1,4,5,6-tetrahydro-6-oxo-1,2,4-triazine-4-carboxamides are recyclized to 5-alkyl-3-ethylhydantoins.
