Visible-light-induced heterogeneous photocatalysis for decarboxylative alkynylation has been performed. The using of cheap, metal-free and recyclable graphitic carbon nitride (g-C3N4) as the photoredox catalyst in the process enables
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.
Gold(I)-catalyzed rearrangement of propargyl benzyl ethers: A practical method for the generation and in situ transformation of substituted allenes

A series of benzyl propargyl ethers react with a gold(I) catalyst to furnish variously substituted allenes via a 1,5-hydride shift/fragmentation sequence. This transformation is rapid and practical. It can be performed under very mild conditions (room temperature or 60 °C) using terminal as well as substituted alkyne substrates bearing a primary, secondary, or tertiary benzyl ether group. The allenes thus formed can be reacted in situ with an internal or external nucleophile, corresponding to an overall reductive substitution process, to produce more functionalized compounds.
