The anticancer ruthenium-arene compd. [Ru(η6-C6H5CF3)(pta)Cl2] (pta = 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane), termed RAPTA-CF3, with the electron-withdrawing α,α,α-trifluorotoluene ligand, is one of the most cytotoxic RAPTA compds. known. To ration ...
Carbon-carbon bond forming reactions are among the most important and useful methods for organic synthesis. During the last years, significant progress has been made in this field. Whereas many catalysts were developed for the coupling of aryl, alkenyl, an ...
A series of organometallic compds. of general formula [(arene)M(PTA)nXm]Y (arene = η6-C10H14, η-C5Me5); (M = Ru(II), Os(II), Rh(III) and Ir(III); X = Cl, mPTA; Y = OTf, PF6) have been screened for their cytotoxicity and ability to inhibit cathepsin B in vi ...
(2,6-Dichlorophenyl)trimethyl- and triethylsilane exhibit untypical reactivity patterns toward strong bases: when treated at -100 °C with lithium 2,2,6,6-tetramethylpiperidide two, with sec- or tert-butyllithium even three organometallic intermediates are ...
(2,6-Dichlorophenyl)trimethyl- and -triethylsilane exhibit untypical reactivity patterns toward strong bases. When treated at -100 DegC with lithium 2,2,6,6-tetramethylpiperidide, they give rise to two, with sec- or tert-butyllithium even three, different ...
Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these complexes can be prepared in pure form in ...
The use of organometallic reagents for functionalization of arenes and heterocycles has recently been renewed by our group. The use of bulky trialkylsilyl groups allows one to shield an acidic position by steric hindrance and the introduction of a chlorine ...
The metalation of 2,3-, 2,6-, 2,4- and 3,5-dichlorobenzotrifluorides can be readily effected with std. reagents such as lithium diisopropylamide, lithium 2,2,6,6-tetramethylpiperidide, and butyllithium at the chlorine-adjacent 4- and 3-positions and the ch ...
The present thesis work concerns the preparation and optionally site selective functionalization of five- and six-membered nitrogen heterocycles and the investigation of atropisomerism of α,o-bis(methoxymethyl)-1-phenylindole. Mono- and disubstituted 2-bro ...
Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...
