In this paper,the synthesis of some new 5-arylfurfurals,their derivatives and dialkyl-5-aryl-2-furoylhydroxymethanephosphonate are reported. The reaction of 5-arylfurfurals with dialkylphosphonates gives dialkyl-5-ary 1-2 -furoylhydroxymethan phosphonate under the triethylamine catalysis condition. Oxidation reaction of 5-arylfurfurals with bromine water,hydrogen peroxide and potassium permanganate give different aromatic acids.The reacion of 5-arylfur- furals with cyclohexanone gives 2,6-bis-(p-acetyl-phenylfurylidene)-cyclohex- anone and 2,6-bis-(o-carboxyl-phenylfurylidene)-cyclohexanone. The structures of all the new compounds are confirmed by IR an delemental analysis.
