The homoleptic compounds [U(salan-R2)2] (R = Me (1), tBu (2)) were prepared in high yield by salt-metathesis reactions between UI4(L)2 (L = Et2O, PhCN) and 2 equiv of [K2(salan-R2)] in THF. In contrast, the reaction of the tetradentate ligands salan-R2 wit ...
Multicomponent reactions between 1,4-benzenediboronic acid, catechol, and different pyridyl ligands are reported. The condensation of 1,4-benzenediboronic acid with catechol gives 1,4-bis(benzodioxaborole)benzene. Upon crystallization, the ester aggregates ...
The application of fluorescent receptor ligands has become widespread, incited by two important reasons. “Seeing is believing”—it is possible to visualize in real time in live cells ligand–receptor interactions, and to locate the receptors with subcellular ...
Chemosensors based on indicator displacement were developed for the optical detection of different analytes in aqueous solution. The sensing of carbohydrates, including glucose, in aqueous solution at pH 7.4 was achieved by a fluorescent indicator displace ...
The development of efficient chiral monodentate phosphine ligands lags behind that of the bidentate congeners. This holds especially true for highly electron rich chiral phosphine analogues able to replace the ubiquitous tricyclohexylphosphine and tri-tert ...
Magnetic resonance imaging (MRI) technique is at the forefront of biomedical and clinical imaging. Its superb spatial resolution, noninvasive nature and use of benign radiation outweigh its intrinsic low detection sensitivity. However paramagnetic relaxers ...
Two tridentate pyridine-tetrazolate ligands (H 2pytz and H 2pytzc), analogues of the well-known dipicolinate (H 2dpa) ligand, have been synthesized in a straightforward manner and used for lanthanide(iii) coordination. The structures of the resulting tris- ...
This work describes the synthesis and characterization of boronic acid-based supramolecular structures. Different reversible interactions such as boronate ester formation, imine condensation and dative B–N bond formation are used to assemble macrocycles, c ...
Native coordinating ligands acquired during the chem. synthesis of colloidal nanocrystals are optimized primarily for their ability to exert control over nanocrystal size, compn., morphol., and dispersibility, and not necessarily for their final applicatio ...
Ru-II(arene) complexes of the general formula [Ru-II(eta(6)-p-cymene)(PPh3)(L)Cl]PF6 with L = P- or N-donor systems have been synthesized and characterized. Carbohydrate-derived phosphites, imidazole or indazole have been chosen as co-ligands and different ...
