New derivatives of 4(3H)-oxobenzo-2,1,3-thiadiazine-2,2-dioxide and compositions and methods employing the same in the control of undesired broadleaf vegetation.
摘要:
1-H-2,1,3-benzothiadiazine-3,4-dihydro-2,2-dioxides are prepared by the reaction of trioxane with N-aryl N'-alkylsulfamides in an organic solvent containing a sulfonic acid at -20.degree. to 80.degree. C.
摘要:
Thiadiazin-5-one compounds of the formula ##STR1## wherein R.sup.1 is alkyl and R.sup.2 is alkyl, alkenyl, cycloalkyl or aryl are prepared by reacting a thiosemicarbazide and an alkyl alpha-halothioacetate. Addition of a dialkylhalothiophosphate to the thiadiazin-5-one compounds produces useful thiadiazine insecticides.
摘要:
New and valuable substituted 2,1,3-benzothiadiazine compounds having a good herbicidal action, herbicides containing these active ingredients, methods of controlling the growth of unwanted plants with these compounds, and processes for manufacturing them.
摘要:
Thiadiazine compounds of the formula (I) ##STR1## wherein R.sup.1 is alkyl, R.sup.2 is alkyl, cycloalkyl, alkenyl or aryl, R.sup.3 is alkyl and R.sup.4 is alkyl, are useful as insecticides. The thiadiazine compounds are prepared by the addition of a dialkylhalothiophosphate to a tetrahydro-6H-1,3,4-thiadiazin-5-one.
摘要:
Compounds of the formula: ##STR1## in which R is an optionally substituted heterocyclic ring having 6 members and containing 1 or 2 hetero N atoms, their fungicidal use and preparation are described and exemplified.
摘要:
New and Valuable substituted 2,1,3-benzothiadiazin-(4)-one-2,2-dioxides having a good herbicidal action and a process for controlling the growth of unwanted plants with these compounds.
摘要:
PRODUCTION OF 2,1,3-BENZOTHIADIAZIN-4-ONE-2,2-DIOXIDES BY CYCLIZATION OF AN O-SULFAMIDOBENZOIC ACID IN THE PRESENCE OF PHOSGENE AND A DISUBSTITUTED CARBOXAMIDE OR A TERTIARY AMINE AT A TEMPERATURE OF NOT MORE THAN 50*C. THE PRODUCS ARE PLANT PROTECTION AGENTS AND STARTING MATERIALS FOR THE PRODUCTION OF DYES AND PLANTS PROTECTION AGENTS.
