The invention describes an improved method for producing halo-dialkoxybenzenes of formula (I) such as 1-fluoro-2, 3-dialkoxybenzene as well as 2-fluoro-1, 4-dialkoxybenzene, Formula (I) by reacting commercial 2-fluorophenol is reacted with an allyl halide in N-methylpyrrolidone (NMP) followed by rearranging the resultant 2-fluoroallylphenylether to form 2-allyl-6-fluorophenol and its para isomeric counterpart. This compound mixture is then directly alkylated to form isomeric substituted allyl alkoxybenzenes and subjected to isomerization to form the corresponding propenyl derivatives. All the above four steps are carried out without any workup except one filtration. 6-Fluoro-2-propenyl alkyl phenyl ether is separated from the other isomer by a fractional distillation in good yields. The isomers are oxidized to the corresponding benzaldehydes using oxidants in presence of a halo hydrocarbon solvent. The benzaldehydes is further oxidised with an organic or an inorganic peroxide in a halo hydrocarbon solvent to obtain the corresponding phenols, which is thereby alkylated to form compound of formula (I).
