The synthesis and in vitro anticancer activity of OsII-arene complexes with carbohydrate-derived phosphite co-ligands are reported. The compds. were characterized by std. methods and the mol. structure of dichlorido(η6-p-cymene)(3,5,6-bicyclophosphite-1,2- ...
A fast method for crystal structure determination Using crystal structure prediction and solid-state H-1 NMI is presented. This technique does not need any prior knowledge except the chemical formula; resonance assignment is not necessary. Starting from an ...
Enantioselective rhodium(I)-catalyzed reactions of tert-cyclobutanols, e.g. I, lead to indanones with quaternary stereogenic centers, e.g. II, via consecutive C-C/C-H/C-C bond activations. ...
The β-diketiminate class of ligands is renowned for the stabilization of coordinatively unsatd. main-group and transition metal complexes. Moreover, the application and scope of transition metal β-diketiminate complexes in the catalytic transformation of o ...
The activation of carbon-carbon σ bonds is a complementary method to access uncommon and difficult-to-prep. organometallic species. Herein, we describe the activation of tert-cyclobutanols through an enantioselective insertion of a chiral rhodium(I) compl ...
A rhodium-catalyzed enantioselective insertion into the C-C bond of tert-cyclobutanols and subsequent proto-demetalation provides access to Me substituted quaternary stereogenic centers in excellent yields and enantioselectivities. The reaction was used fo ...
The size of a series of typical substituents has been probed by dynamic NMR measurements of the barriers to aryl-aryl rotation of the corresponding biphenyls. The resulting B values are meaningful because only mono-ortho substituted compounds were investig ...
A review. The catalytic activation of C-C single bonds represents a major challenge in organometallic chem. Strained ring substrates occupy in this respect a privileged role as their inherent ring strain facilitates the desired metal insertion. Employing s ...
We demonstrate that it is possible to record site-specific spin-lattice relaxation rates for the majority of C-13 sites in uniformly C-13 and N-15 labeled solid proteins as a result of the slowing down of proton-driven spin diffusion at sample spinning fre ...
Metal complexes bearing phosphine ligands are attracting increasing attention for their applications in medicinal chem. In particular, organometallic ruthenium-phosphine complexes have been found to exhibit promising antitumor activity. The synthesis, anti ...
