Abstract

IN RECENT YEARS THE THREE-COMPONENT REACTIONS OF TRIPHENYLPHOSPHINE, ELECTRON-DEFICIENT SYSTEMS AND XHACIDS (X=C, O, N, S) THAT LEADS TO PHOSPHORUS YLIDES HAVE BEEN REPORTED. THESE YLIDES ARE FINAL PRODUCTS OF REACTIONS OR INTERMEDIATES IN OTHER SYNTHESES.WE HERE REPORT THE REACTION OF 3- (2, 4-DINITROPHENY) -2, 4-PENTANEDIONE2 (ACTING AS A CH-ACID) AND DIALKYLACETYLENEDICARBOXYLATES1 IN THE PRESENCE OF TRIPHENYLPHOSPHINE. THESE COMPOUNDS UNDERGO INTRAMOLECULAR WITTIG REACTION IN ROOM TEMPERATURE TO PRODUCE CYCLOBUTENES, WHICH SPONTANEOUSLY UNDERGO RING-OPENING REACTION TO PRODUCE DIASTEREOMERIC 1, 3- DIENE ISOMERS3 IN MIDDLING YIELDS. THE STRUCTURE OF COMPOUNDS IS SUPPORTED WITH SPECTRAL DATA (1HNMR, 13CNMR, IR) AND ELEMENTAL ANALYSIS.
