摘要：
The present invention deals with 2-(substituted- imino)-3-alkyl-tetrahydro-6H-1,3,4-thiadiazin-5-ones, salts thereof, their preparation and their use for preparing corresponding 5-dialkoxy-phosphino-thioloxy compounds, which are valuable insecticides.
The thiadiazinone compounds of the invention have the
wherein R' is alkyl and R 2 is alkyl, cycloalkyl, alkenyl or aryl. They are prepared by reacting a thiosemicarbizide with an alkyl alpha-halothioacetate or with a haloacetic anhydride.
These thiadiazin-5-ones are useful for preparing, by the addition of a dialkylhalothiophosphate, 2-(substituted- imino)-3-alkyl-5-dialkoxyphosphinothioloxy-6H-1,3,4-thiadiazines which are valuable insecticides.
