- Iridium Pincer-Catalyzed Dehydrogenation of Ethers Featuring Ethylene as the Hydrogen Acceptor
-
We describe efficient methods to dehydrogenate ethers by using iridium pincer complexes (iPr4Anthraphos)-Ir(H)(Cl), 4, iPr4PC(sp3)P-Ir(H)(Cl), 5, and (iPr4PCP)-Ir(H)(Cl), 6. At 120°C, cyclic ethers were dehydrogenated with tert-butylethylene as the hydrogen acceptor with high turnover numbers (over 400 in many cases). Acyclic ethers such as diethyl ether can also be dehydrogenated catalytically with TONs up to 90. The efficient dehydrogenation of cyclic and acyclic ethers using ethylene as a more practical hydrogen acceptor has been demonstrated for the first time. (Figure Presented)

- The (η6-Naphthalene)(η4-cycloocta-1,5-diene)ruthenium(0) Complex as Precursor for Homogeneous and Heterogeneous Catalysts in the Isomerization of Allyl Ethers and Allyl Acetals to Vinyl Derivatives
-
The complex (η6-naphthalene(η4-COD)ruthenium(0), I, (COD=cycloocta-1,5-diene), in the presence of acetonitrile, easily catalyzes the isomerization of allyl ethers and allyl acetals, having different steric and electronic features, to

- IRIDIUM PENTAHYDRIDE COMPLEX CATALYZED FORMATION OF C-C BOND BY C-H BOND ACTIVATION FOLLOWED BY OLEFIN INSERTION
-
The formation of carbon-carbon bond was found to occur by first carbon-hydrogen bond activation followed by olefin insertion under the catalysis of an iridium pentahydride complex.
