Chemistry and Application of Phosphonium or Arsonium Ylides (XIV)——Reaction of Phosphonium or Arsonium Ylides with Methyl Propynoate and Hydrolysis of Some Adducts

Abstract

Abstract: Reaction of nine Ylides, carbomethoxymethylenetriphenylarsine (1b), benzoylmethy-lenetriphenylphosphine, arsine, acetylmethylenetriphenylphosphine, arsine, cyanomethylen-etriphenylphosphine, arsine, p-nitrophenylmethylenetriphenylphosphine (li) and 1-methyl-2-car-boethoxymethylenetriphenylphosphorane with methyl propynate(2) was studied. The hydrolysis of the adducts l,3-dicarbomethoxy-2-propenylenetriphenyl arsorane(3b) and.1-carbomethoxy-3-p-ni-trophenyl-2-propenylenetriphenylphosphorane(3i) which are the reaction products of 1b and li with 2 respectively was also studied in aqueous methanol.

Key words: Phosphonium Ylide, Arsonium Ylide, Methyl propynoate, Hydrolysis
