Stille-type aryl-aryl cross-coupling catalysis using triarylphosphine ligands with electron-rich Fe(II)-alkynyl substituents

Résumé

The synthesis of four new phosphane ligands featuring electron-rich Fe(II) "(η2-dppe)(η5-C5Me5)FeC[triple bond, length as m-dash]C-" substituents in para and meta position(s) on the aryl rings (1-4) is reported along with those of the corresponding PdCl2(PAr3)2 precatalysts (7-10). These precatalysts have then been tested in a Stille-type aryl-aryl cross coupling reaction. It is shown that these new ligands survive the reaction conditions and perform at least as well as the classic triphenylphosphine ligand for this transformation.
