A NEW METHOD FOR ONE-POT SYNTHESIS OF ARYLOXYPHENOXYPROPIONATE HERBICIDES USING 2,4,6-TRICHLORO-1,3,5-TRIAZINE AND (n-BU)4NI AS A HOMOGENEOUS CATALYST
摘要:
The one-pot reaction of halo-heterocycle, (R)-4-hydroxyphenoxy propionic acid and an alcohol, amine or sulfonamide is described as an efficient method for the synthesis of aryloxyphenoxy propionate hrerbicides by using 2,4,6-trichloro-1,3,5-triazine in the presence of (Bu-n)(4)NI, as a homogeneous catalyst under mild conditions. The present procedure offers several advantages, such as good yields, short reaction times and easy workup.
