Ketone Hydrogenation with Iridium Complexes with “non N–H” Ligands: The Key Role of the Strong Base [PDF]
, 2015 Ferrocenyl phosphine thioether ligands (PS), not containing deprotonatable functions, efficiently support the iridium catalyzed ketone hydrogenation in combination with a strong base co-catalyst. Use of an internal base ([Ir(OMe)(COD)]2 in place of [IrCl(

Niobium Pentamethoxide: a Multi-facet Study of an Early Transition Metal Alkoxide
CHIMIA, 1976 Niobium pentamethoxide, Nb2(OCH3)10, was chosen as a typical early transition metal alkoxide on which to undertake a multifacet study, including such aspects as crystal and molecular structure, exchange of methoxo groups among coordination sites ...

Stable hydrosols for TiO2 coatings [PDF]
, 2010 The optimum processing parameters required to synthesize, by hydrolysis of titanium isopropoxide (TIP), highly stable hydrosols composed of nanoparticles of the smallest possible size, are deduced both from data available in literature and from our own ...

Preparation of Ni–YSZ thin and thick films on metallic interconnects as cell supports. Applications as anode for SOFC [PDF]
, 2008 In this work, we propose the preparation of a duplex anodic layer composed of both a thin (100 nm) and a thick film (10 lm) with Ni–YSZ material. The support of this anode is a metallic substrate, which is the interconnect of the SOFC unit cell.

Synthesis and structure of a new bulky bis(alkoxide) ligand on a terphenyl platform
Acta Crystallographica Section E: Crystallographic Communications, 2022 A new sterically bulky chelating bis(alkoxide) ligand 3,3′-([1,1′:4′,1′′-terphenyl]-2,2′′-diyl)bis(2,2,4,4-tetramethylpentan-3-ol), (H2[OO]tBu), was prepared in a two-step process as the dichloromethane monosolvate, C36H50O2·CH2Cl2.

Surprisingly facile CO2 insertion into cobalt alkoxide bonds: A theoretical investigation
Beilstein Journal of Organic Chemistry, 2015 Exploiting carbon dioxide as co-monomer with epoxides in the production of polycarbonates is economically highly attractive. More effective catalysts for this reaction are intensively being sought.
