摘要:
1-Phenyl-2-(1,2,4-triazol-1-yl)-ethyl ethers of the formula ##STR1## in which R is halogen, alkyl, alkoxy, alkylthio, alkylsulfonyl, halogenoalkyl, nitro, cyano, optionally substituted phenyl or optionally substituted phenoxy,R' is alkyl, alkenyl, alkynyl, optionally substituted phenyl, optionally substituted benzyl or optionally substituted styryl, andn is 0, 1, 2 or 3,and their salts, which possess fungicidal and bactericidal properties.
摘要:
Novel glyoxylic acid hydrazide-2-acylhydrazones of the formula: ##STR1## in which R.sup.1 is hydrogen or alkyl, andR.sup.2 is alkyl or optionally substituted phenylAnd are prepared by reacting the corresponding glyoxylic acid ester 2-acylhydrazone with hydrazine hydrate. The compounds (I) are useful in preparing herbicidally active 4-amino-1,2,4-triazine-5-one compounds.
摘要:
.alpha.-Oxothiodimethylamide compounds such as tert.-butyl-glyoxyl acid thiodimethylamide are prepared by reacting an .alpha.-chloroketone of the formula ##STR1## in which X is hydrogen or chlorine andR.sup.1 is alkyl or arylWith sulfur and dimethylamine in water at a temperature between 50.degree. and 90.degree. to produce the corresponding .alpha.-oxothiodimethylamide of the formula ##STR2## wherein R.sup.1 is identified above.

摘要:
Novel 3,4-dihydro-1,2,4-triazine compounds of the formula ##SPC1##In whichR.sup.1 is alkyl or cycloalkyl;R.sup.2 is methyl, amino, alkylideneamino, methylamino, .beta.-hydroxyethylamino, 2-furylmethylamino, aralkylamino or substituted aralkylamino; and R.sup.3 is alkyl, aryl or substituted aryl;Are prepared by reacting the corresponding 1,2,4-triazin-5-one with sodium borohydride in the presence of a polar solvent at a temperature between -10.degree. and +25.degree.C. The novel compounds are outstandingly effective as herbicides and display particularly selective action.
