The ability to convert phosphorus (III) to phosphorus (V), the relatively strong bonds between phosphorus and oxygen and sulfur atoms, and the presence of the empty ۳d orbital in the phosphorus atom have made organic phosphorus reactants widely used in the synthesis of organic matter. Important phosphorus reactors include phosphorus alloys, which are used in the synthesis of many organic compounds. Phosphorus ylide exhibits chemical behavior similar to sacrifice. Participates in both additive and substitution reactions. Numerous reports in magazines show the importance of Wittig-Horner's reactions. The wittig-horner reaction is one of the most interesting organic chemical reactions for the synthesis of alkenes. In this method, alkylidyne phosphors react with aldehydes or ketones to produce olefins. In this paper, the aim was to successfully synthesize alkyl-۲-oxo-۲H-chromen-۴- yl-۲-butenedioate derivatives by the wittig-horner mechanism. The structure of the obtained compounds was analyzed by FTIR, ۱HNMR, ۱۳CNMR.
