PURPOSE: The reaction is effected by adding dialkyl 9-anthrylmethylphosphonate and a solution of aldehyde into a dispersion or solution of strong-base alkaline compound to produce title compound useful as a photoconductive substance in high purity. n CONSTITUTION: The reaktion between a compound of formula I (X is H, halogen; R 1 is 1W4C alkyl) and an aldehyde of formula II (R 2 is aromatic residue that may be substituted or heterocycle residue as N-ethylcarbazolyl) is carried out by adding them into a dispersion or solution of a strong-base alkali compound as lithium hydroxide or sodium hydroxide at 10W180°C. n EFFECT: No by-product insoluble or hard soluble is formed and the objective compound can be obtained in high yield. Further, the product is advantageous in costs because it can be readily made from readily available raw materials. n COPYRIGHT: (C)1979,JPO&Japio |
