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.

A novel, efficient, and highly regioselective Lewis acid-catalyzed [3 + 2] cycloaddition of alkynes with azomethine ylides, which are easily obtained from N-tosylaziridines via C-C bond heterolysis at room temperature was developed. Moderate enantioselect
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.
