Facile synthesis of 3(2H)-furanones

Abstract: A practical method for the synthesis of 3(2H)-furanones including the bullatenone was described. Intramolecular cyclization of 4-hydroxyalkynones in the presence of KOH affords the biologically potent furanones in moderate-to-good yield at room temperature. Synthesis of 4-hydroxyalkynones from the reaction of acid chloride and terminal alkyne in the presence of copper iodide at room temperature was also reported.

PHOSPHINE COMPOUND HAVING PERFLUORO GROUP, AND COMPLEX BETWEEN METAL AND PHOSPHINE HAVING PERFLUORO GROUP

PROBLEM TO BE SOLVED: To provide a perfluoroalkylphosphine compound, and a complex between a metal and the perfluoroalkylphosphine. SOLUTION: A perfluoroalkylphosphine compound is a phosphine compound represented by the general formula Rf-PR1R2. In the formula, R1 and R2 are each independently a substituted or unsubstituted hydrocarbon group; Rf is a perfluorinated hydrocarbon group. Also provided is a complex between the perfluoroalkylphosphine and a phosphine coordination metal. SELECTED DRAWING: None COPYRIGHT: (C)2016,JPOandINPIT

Photoinduced Synthesis of P-Perfluoroalkylated Phosphines from Triarylphosphines and Their Application in the Copper-Free Cross-Coupling of Acid Chlorides and Terminal Alkynes

A practical synthesis yielding P-perfluoroalkylated phosphines from triarylphosphines and perfluoroalkyl iodides has been developed. The photoinduced reaction involves the substitution of aryl groups on the phosphorus atom with perfluoroalkyl groups to successfully afford P-perfluoroalkylated phosphines. In addition, the P-perfluoroalkylated phosphines were found to promote the Cu-free cross-coupling reaction of acid chlorides with terminal alkynes.
