摘要:
NEW 1,2,3,7 - TETRAHYDRO-(1,2,4)TRIAZOLO(3,2-C)(1,2,4)TRIAZINONE-(7) COMPOUNDS OF THE FORMULA

2-R2,2-R3,3-R4,6-R1,7-(O=)-1,2,3,7-TETRAHYDRO-(1,2,4)-

TRIAZOLO(3,2-C)(1,2,4)TRIAZINE

IN WHICH:

R1 IS HYDROGEN, SUBSTITUTED OR UNSUBSTITUTED ALKYL, ALKENYL, CYCLOALKYL, ARALKYL OR ARYL; R2 AND R3 INDIVIDUALLY ARE HYDROGEN, SUBSTITUTED OR UNSUBSTITUTED ALKYL, ALKENYL, CYCLOALKYL, CYCLOALKENYL OR ARALKYL; AND R2 AND R3 TAKEN TOGETHER, ARE ALKYLENE OF FROM 4 TO 7 RING CARBON ATOMS WHICH MAY CARRY ONE OR MORE ALKYL GROUP SUBSTITUENTS, AND R4 IS HYDROGEN, ALKYL, ALKENYL, ARALKYL OR SUBSTITUTED OR UNSUBSTITUTED SRYL

ARE PREPARED BY A NOVEL SYNTHESIS BY REACTING THE CORRESPONDING DIAMINO DIHYDRO TRIAZINONE COMPOUND WITH AN OXO COMPOUND OF THE FORMULA

R2-CO-R3

IN THE PRESENCE OF A LOWER ALKANOIC ACID. THE NOVEL COMPOUNDS ARE OUTSTANDINGLY EFFECTIVE AS HERBICIDES, E.G., AS SELECTIVE HERBICIDES.
