Fecha de publicación: | 29-ene-2020 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Molecules 25(3): 593 (2020) | Resumen: | A straightforward method for the preparation of trisphosphinite ligands in one step, using only commercially available reagents (1,1,1-tris(4-hydroxyphenyl)ethane and chlorophosphines) is described. We have made use of this approach to prepare a small family of four trisphosphinite ligands of formula [CH3C{(C6H4OR2)3], where R stands for Ph (1a), Xyl (1b, Xyl = 2,6-Me2-C6H3), iPr (1c), and Cy (1d). These polyfunctional phosphinites allowed us to investigate their coordination chemistry towards a range of late transition metal precursors. As such, we report here the isolation and full characterization of a number of Au(I), Ag(I), Cu(I), Ir(III), Rh(III) and Ru(II) homotrimetallic complexes, including the structural characterization by X-ray diffraction studies of six of these compounds. We have observed that the flexibility of these trisphosphinites enables a variety of conformations for the different trimetallic species. | Descripción: | This article belongs to the Special Issue Advances in Coordination Chemistry. | Versión del editor: | https://doi.org/10.3390/molecules25030593 | URI: | http://hdl.handle.net/10261/199693 | DOI: | 10.3390/molecules25030593 | E-ISSN: | 1420-3049 |
