The symmetrical bisferrocene 1,1,14,14-tetra-n-butyl-2,2,13,13,15,15,26,26-octamethyl-1,2,13,14,15,26-hexastanna[3.3]ferrocenophane ([(η5-C5H4)Fe(η5-C5H4SnMe2Sn(n-Bu)2SnMe2)]2, 8) was synthesized in good yield (82%) from the reductive coupling reaction of 1,1′-bis(dimethylstannyl)ferrocene, ...
Photoswitchable Organoplatinum(IV) Complexes
30-04-2013 | Mohamed E. Moustafa; Matthew S. McCready; Richard J. Puddephatt, Organometallics, 2013
Organoplatinum(IV) complexes, [PtBrMe2(CH2-4-C6H4-N═N-Ph)(NN)], containing trans-azobenzene functional groups, have been prepared by trans oxidative addition of BrCH2-4-C6H4-N═N-Ph to the corresponding platinum(II) complexes [PtMe2(NN)], with NN = 2,2′-bipyridine, 1,10-phenanthroline, ...
Cationic Dihydride Boryl and Dihydride Silyl Osmium(IV) NHC Complexes: A Marked Diagonal Relationship
29-04-2013 | Marı́a L. Buil; Miguel A. Esteruelas; Israel Fernández; Susana Izquierdo; Enrique Oñate, Organometallics, 2013
The complex [OsCl(η6-p-cymene)(IPr)]OTf (1; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene, OTf = trifluoromethanesulfonate) reacts with pinacolborane (HBpin) and catecholborane (HBcat) to give the dihydride boryl osmium(IV) derivatives [OsH2(Bpin)(η6-p-cymene)(IPr)]OTf (2) and ...
Synthesis and Photophysical Properties of Asymmetric Substituted Silafluorenes
26-04-2013 | Erika Pusztai; Irina S. Toulokhonova; Nicole Temple; Haley Albright; Uzma I. Zakai; Song Guo; Ilia A. Guzei; Rongron ..., Organometallics, 2013
Several 1,3-diphenyl-substituted silafluorene compounds were synthesized and characterized as potential fluorescent materials for OLED fabrication and bioimaging. Introducing phenyl groups into the silafluorene ring at the 1- and 3-positions led to a red shift in the emission, resulting in ...
Insight into the Hydrogen Migration Processes Involved in the Formation of Metal–Borane Complexes: Importance of the Third Arm of the Scorpionate Ligand
26-04-2013 | Nikolaos Tsoureas; Alex Hamilton; Mairi F. Haddow; Jeremy N. Harvey; A. Guy Orpen; Gareth R. Owen, Organometallics, 2013
The reactions of [Ir(κ3N,N,H-Tai)(COD)] and [Ir(κ3N,N,H-PhBai)(COD)] (where Tai = HB(azaindolyl)3 and PhBai = Ph(H)B(azaindolyl)2) with carbon monoxide result in the formation of Z-type iridium–borane complexes supported by 7-azaindole units. Analysis of the reaction mixtures involving the ...
2,6-Diisopropylphenylamides of Potassium and Calcium: A Primary Amido Ligand in s-Block Metal Chemistry with an Unprecedented Catalytic Reactivity
16-04-2013 | Carsten Glock; Fadi M. Younis; Steffen Ziemann; Helmar Görls; Wolfgang Imhof; Sven Krieck; Matthias Westerhausen, Organometallics, 2013
Transamination of KN(SiMe3)2 with 2,6-diisopropylphenylamine (2,6-diisopropylaniline) in toluene at ambient temperature yields [K{N(H)Dipp}·KN(SiMe3)2] (1) regardless of the applied stoichiometry. Recrystallization of 1 in the presence of tetramethylethylenediamine (TMEDA) and tetrahydrofuran ...
Synthesis and Reactions of a Hybrid Tristibine Ligand
15-04-2013 | Sophie L. Benjamin; William Levason; Gillian Reid, Organometallics, 2013
The tripodal tristibine N(CH2-2-C6H4SbMe2)3 (L) has been prepared in high yield and characterized by 1H and 13C{1H} NMR spectroscopy and elemental analysis. A range of reactions with transition-metal acceptors were carried out to probe the coordinative properties of L. The 3/1 M/L complex ...
Unusual Reactivity of a C,N-Chelated Stannylene with Siloxanes and Silanols
08-04-2013 | Zdeňka Padělková; Petr Švec; Hana Kampová; Jan Sýkora; Miloslav Semler; Petr Štěpnička; Snejana Bakardjieva; Rudolph ..., Organometallics, 2013
The reactivity of stannylene (LCN)2Sn (1), where LCN is the 2-(N,N-dimethylaminomethyl)phenyl substituent, toward (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO), silicon grease, and triphenylsilanol was explored. The reaction of 1 with one equivalent of TEMPO and silicon grease yielded ...
Metal-Centered 17-Electron Radicals CpM(CO)3• (M = Cr, Mo, W): A Combined Negative Ion Photoelectron Spectroscopic and Theoretical Study
25-03-2013 | Edwin F. van der Eide; Gao-Lei Hou; S. H. M. Deng; Hui Wen; Ping Yang; R. Morris Bullock; Xue-Bin Wang, Organometallics, 2013
Despite the importance of group 6 metal-centered 17-electron radicals CpM(CO)3• (M = Cr, Mo, W) in establishing many of the fundamental reactions now known for metal-centered radicals, spectroscopic characterization of their electronic properties and structures has been very challenging, due ...
Synthesis and Characterization of Group 4 Permethylpentalene Dichloride Complexes
