Abstract
- 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 [CH <subscript>3</subscript> C{(C <subscript>6</subscript> H <subscript>4</subscript> OR <subscript>2</subscript> ) <subscript>3</subscript> ], where R stands for Ph ( 1a ), Xyl ( 1b , Xyl = 2,6-Me <subscript>2</subscript> -C <subscript>6</subscript> H <subscript>3</subscript> ), <superscript>i</superscript> Pr ( 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.
