Phenolic derivatives can be formylated in the ortho position selectively. In this research at first magnesiumphenoxide was synthesised by the reaction of white powder of magnesium methoxide and phenol in toluene as a nonpolar solvent. Secondly para-formaldehyde was reacted with magnesium phenoxides. The resulting product was purified after several times washing with acid and distilled water and then its characterization byMS and FTIR spectrum analysis. FTIR spectrum deliberation shows the good orthoselectivity of the product. MS spectrum Deliberation shows an ionic peak in m/z 122 as phenolic base peak and with abundances of 100%, another peak in m/z 121 with abundance of 93.75 elucidate the elimination of phenolic proton % and the final peak in m/z 93 with abundance of 87.5 assigned to the elimination of CHO from deprotonated phenol. These analyzing which has less been asserted in the articles show the synthesis of product with this method besides of having high orthoselectivity has about 87% yields.
