Pd- and Cu-catalyzed approaches in the syntheses of new cholane aminoanthraquinone pincer-like ligands

چکیده
Cu- and Pd-catalyzed arylation of aminocholanes has been described for the first time. While this Cu-catalyzed protocol provides high yields in reactions of aminocholanes with iodoarenes, Pd catalysis was found to be preferable for the reactions of aminocholanes with dichloroanthraquinones. UV-vis titration of bis(cholanylamino)anthraquinones with a series of cations demonstrated their high binding affinity to Cu2+, Al3+, and Cr3+.

Syntheses, Characterization and Solvatochromism Study of Heteroleptic Chelated Copper(II) Complexes Containing N,N- dibezyl Substituted Ethylenediamine and Acetylacetonate Ligands
A series of new heteroleptic chelated copper(II) complexes that encompass N,N-dibezyl substituted derivative of ethylenediamine (X-diamine) and acetylacetonate (acac) were prepared. The IR and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed. The molar conductivity values of the complexes in different solvents reveals a predominance of elec...
متن کاملThe mechanism of transition-metal (Cu or Pd)-catalyzed synthesis of benzimidazoles from amidines: theoretical investigation.
In this study, the Cu(OAc)2- and [PdCl2(PhCN)2]-catalyzed syntheses of benzimidazoles from amidines were theoretically investigated using density functional theory calculations. For the Cu-catalyzed system, our calculations supported a four-step-pathway involving C-H activation of an arene with Cu(II) via concerted metalation-deprotonation (CMD), followed by oxidation of the Cu(II) intermediate...
متن کاملSulfur-functionalized N-heterocyclic carbene complexes of Pd(II): syntheses, structures and catalytic activities.
N-heterocyclic carbenes (NHCs) can be easily modified by introducing functional groups at the nitrogen atoms, which leads to versatile coordination chemistry as well as diverse catalytic applications of the resulting complexes. This article summarizes our contributions to the field of NHCs bearing different types of sulfur functions, i.e., thioether, sulfoxide, thiophene, and thiolato. The expe...
متن کاملCatalyst-controlled chemoselective arylation of 2-aminobenzimidazoles.
The chemoselective and complementary Pd-and Cu-catalyzed N-arylation of 2aminobenzimidazoles is described. Selective N-arylation of the amino-group was achieved with a Pd-catalyzed method, while selective N-arylation of azole nitrogen was achieved with a Cucatalyzed procedure. The utility of these complementary sets of conditions is demonstrated in several two-step, selective syntheses of di-ar...

Furanoids are important targets either as a key entity itself or as a substructure that represents the framework of many biologically significant natural products [1]. Therefore, their access has attracted the interest of many groups [2], Voelter et al. have described elegant strategies for the syntheses of furanoids using two different approaches, either mono or dianions derived from 1,3-dicar...
