Abstract

PHOSPHORUS YLIDES ARE REACTIVE COMPOUNDS, WHICH TAKE PART IN MANY REACTIONS OF VALUE IN THE SYNTHESIS OF ORGANIC PRODUCTS [1]. THEY ARE SYNTHETIC TARGETS OF INTEREST, BECAUSE OF THEIR VALUE FOR A VARIETY OF INDUSTRIAL, BIOLOGICAL AND CHEMICAL SYNTHETIC USES [2]. THE Α-KETO STABILIZED YLIDES DERIVED FROM BISPHOSPHINES, VIZ., PH2P(CH2)NPPH2=C(H)C(O)R (N = 1, 2) (R = ME, PH OR OME) [3] AND PHC(O)C(H)=PPH2(CH2)2PPH2=C(H)C(O)PH [4] FORM AN IMPORTANT CLASS OF HYBRID LIGANDS CONTAINING BOTH PHOSPHINE AND YLIDE FUNCTIONALITIES, AND CAN EXIST IN YLIDIC AND ENOLATE FORMS. THIS COMPOUND WAS PREPARED ACCORDING TO A PUBLISHED METHOD [5]. THE REACTION OF PH2P(CH2)2PPH2 (DPPE) WITH BRCH2C(O)C6H4NO2 IN CHLOROFORM PRODUCES THE PHOSPHONIUM SALT [PH2P(CH2)2PPH2CH2C(O)C6H4NO2]BR. FURTHER, BY REACTING THE PHOSPHONIUM SALT WITH APPROPRIATE BASE THE BIDENTATE PHOSPHORUS YLIDE, PH2P(CH2)2PPH2=C(H)C(O)C6H4NO2 (Y) WAS OBTAINED. THE COMPOUND HAS BEEN CHARACTERIZED BY ELEMENTAL ANALYSIS, IR, 1H, 31P AND 13C NMR. THE STRUCTURE OF Y HAS BEEN DETERMINED BY SINGLE CRYSTAL X-RAY METHOD.
