Zusammenfassung, Abstract
A facile large-scale synthesis of the push-pull-substituted ligand bis(diethylamino)(pentafluorophenyl)phosphine is reported. A selenophosphorane as well as complexes with CuI and PdCl2, can be formed almost quant. from suitable starting materials. The Pd(II) complex shows a square-planar coordination with significant distortions of the Cl-Pd-Cl moiety in the solid state. In contrast, the phosphine ligand exhibits a large flexibility in the trigonal-planar coordination of the Cu salt, as proven by x-ray crystallog. C-C cross-coupling reactions and 1,3-dipolar cycloaddns. were tested for the Pd(II) and Cu(I) complexes, resp. Whereas the reactivity of the Pd(II) complex is good at low temp., the Cu(I) complex reveals remarkable reaction rates at temps. up to 130°. Furthermore, the Cu(I)-catalyzed azide/alkyne 1,3-dipolar cycloaddn. was successfully adapted for flow conditions. [on SciFinder(R)]
