Abstract
Metal-catalyzed hydrofunctionalization reactions of alkynes, i.e., the addition of Y–H units (Y = heteroatom or carbon) across the carbon–carbon triple bond, have attracted enormous attention for decades since they allow the straightforward and atom-economic access to a wide variety of functionalized olefins and, in its intramolecular version, to relevant heterocyclic and carbocyclic compounds. Despite conjugated 1,3-diynes being considered key building blocks in synthetic organic chemistry, this particular class of alkynes has been much less employed in hydrofunctionalization reactions when compared to terminal or internal monoynes. The presence of two C≡C bonds in conjugated 1,3-diynes adds to the classical regio- and stereocontrol issues associated with the alkyne hydrofunctionalization processes’ other problems, such as the possibility to undergo 1,2-, 3,4-, or 1,4-monoadditions as well as double addition reactions, thus increasing the number of potential products that can be formed. In this review article, metal-catalyzed hydrofunctionalization reactions of these challenging substrates are comprehensively discussed.

Abstract
Furans are five-membered aromatic heterocycles containing one oxygen atom that are important
building blocks in organic chemistry, but also as natural products found in various natural
sources, mostly in plants, algae and microorganisms. In this review, we discussed recent advances in the
synthesis of furan compounds. Some classical methods have been modified and improved, while other
new methods have been developed. A vast variety of catalysts was used for these transformations. In
many studies, furan synthesis reaction mechanisms were also investigated and proposed.

Abstract
The title thiophene derivatives bearing two 9-, 1-, or 2-anthryl groups were synthesized by cyclization of the corresponding 1,3-diynes with sodium sulfide or by Suzuki–Miyaura coupling. X-ray analysis and DFT calculations revealed that the molecules adopt nonplanar conformations depending on the steric demand of the anthryl groups. The dihedral angles between the arene units are an important contributor to the photophysical properties in the electronic spectra as well as the electrochemical data.

Abstract
Oxidations of phenylacetic acid to benzaldehyde, benzyl alcohol to benzaldehyde, and benzaldehyde to benzoic acid have been observed, in water as the solvent and using only copper(II) chloride as the oxidant. The reactions are performed at 250 °C and 40 bar, conditions that mimic hydrothermal reactions that are geochemically relevant. Speciation calculations show that the oxidizing agent is not freely solvated copper(II) ions, but complexes of copper(II) with chloride and carboxylate anions. Measurements of the reaction stoichiometries and also of substituent effects on reactivity allow plausible mechanisms to be proposed. These oxidation reactions are relevant to green chemistry in that they proceed in high chemical yield in water as the solvent and avoid the use of toxic heavy metal oxidizing reagents.
