20.500.12556/RUL-167895 Ruthenium-catalyzed transfer hydrogenation of alkynes access to alkanes and (E)- or (Z)‑alkenes in tandem with Pd/Cu Sonogashira cross-coupling A complete reduction of alkynes using a combination of [RuCl$_2$(p-cymene)]$_2$, DTBM-SEGPHOS, and a paraformaldehyde/water system as the hydrogen source was developed, affording alkanes in 52–99% yields. In addition, the preparation of alkenes from terminal alkynes and aryl iodides by a tandem process of Pd/Cu-catalyzed Sonogashira reaction followed by Ru-catalyzed transfer hydrogenation is reported, affording alkenes in 38–99% yields. This multicatalysis proceeds via three consecutive reactions and can be extended further, as shown by adding an iodine-catalyzed cis–trans alkene isomerization step. catalysts ruthenium chemical reactions hydrocarbons hydrogen transfer reactions katalizatorji rutenij kemijske reakcije ogljikovodiki vodik reakcije prenosa true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-19 14:27:41 2025-03-19 14:27:41 2025-03-21 03:57:48 0000-00-00 00:00:00 2025 0 0 Str. 3480-3484 iss. 9 Vol. 90 7 Mar. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 547.31:66.094.25 0022-3263 10.1021/acs.joc.4c01864 229478915 jankovic-et-al-2025-ruthenium-catalyzed-transfer-hydrogenation-of-alkynes-access-to-alkanes-and-(e)-or-(z)-alkenes-in.pdf jankovic-et-al-2025-ruthenium-catalyzed-transfer-hydrogenation-of-alkynes-access-to-alkanes-and-(e)-or-(z)-alkenes-in.pdf 1 1DB7FAA6D9C6428D5E90E34670EB57E0 d64edfe74b3970675e9de57e7eb78107eadd07b9a2560cb5520650fa8db76300 b99b00ed-058f-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200860 https://pubs.acs.org/doi/10.1021/acs.joc.4c01864 1 ec9c29b4-04c4-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200789 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
