Allylation is representing an important C-C bond formation where it introduced new
allyl product. The aim of this study is to synthesized the monoallyl product for
application in herbicide for example Quizalofop-P-ethyl. In this study, monoallyl was
synthesized by the treatment of 1,3-cyclohexadione with allyl halide such as allyl
chloride or allyl bromide. The product of monoallyl was characterized using Fourier-
Transform Infrared (FT-IR). This result shown a positive result where the percentage
yield of monoallyl were increased to 50% compared to previous reported. The result
of IR spectrum shows ν(sp 3 C-H) at 2920.71 cm -1 , ν( C=C ) at 1849.22 cm -1 , ν(C=O)
at 1735.83 cm -1 and allyl ν(C=C) at 861.43 cm -1 . As a conclusion, allyl bromide has
better reactivity to get monoallyl compared to allyl chloride.
