MCM-41-supported bidentate phosphine palladium(0) complex: a highly active and recyclable catalyst for the Sonogashira reaction of aryl iodides

The first MCM-41-supported bidentate phosphine palladium(0) complex has been prepared. This complex is a highly efficient catalyst for Sonogashira reaction and can be reused at least 10 times without any decrease in activity.

C-S Bond Alkynylation of Diaryl Sulfoxides with Terminal Alkynes by Means of a Palladium-NHC Catalyst

Sonogashira-Hagihara-type alkynylation of diaryl sulfoxides with unactivated terminal alkynes has been developed. With a combination of a palladium-NHC catalyst and LiO t Bu as a base, a series of diaryl sulfoxides were converted into the alkynylated products via C-S bond cleavage.

Iron(II) chloride catalyzed alkylation of propargyl ethers: Direct functionalization of an sp3 C-H bond adjacent to oxygen

Iron(II) chloride catalyzed direct alkylation of sp3 C-H bond adjacent to oxygen in propargyl ethers has been accomplished by the use of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as oxidant under mild reaction conditions. The reaction proceeded smoothly with a variety of 1,3-diketones leading to -dicarbonyl ether in moderate yields. In the absence of 1,3-diketones, ynenones were produced by the use of iron(III) chloride and DDQ. Georg Thieme Verlag Stuttgart - New York.

An efficient coupling of aryl iodides with terminal alkynes catalyzed by silica-supported sulfur palladium(0) complex

A silica-supported sulfur palladium(0) complex was prepared by the direct ligand-exchange reaction of poly-γ-mercaptopropylsiloxane with Pd(PPh3)4. It was an efficient catalyst for the coupling of aryl iodides with terminal alkynes.
