چکیده
The in situ reaction of the tripodal anion [EtAl((Me)Py)3](-) ((Me)Py = 6-Me-2-py) with SnCl2 gives the Janus-head ligand ((Me)Py)3Sn-Sn((Me)Py)3, containing a Sn-Sn bond, through a novel, one-pot reaction involving a combination of pyridyl transfer and metal-oxidation.

Sterically-constrained tripodal phosphorus-bridged tris-pyridyl ligands.
Introducing substituents into the 6-position of the 2-pyridyl rings of neutral tris-pyridyl phosphanes of the type P(2-py')3 (where 2-py' is a substituted 2-pyridyl ring), has a marked impact on their coordination of transition metal ions, as revealed in the current study. Whereas the unsubstituted phosphorus-bridged tris-pyridyl ligand P(2-py)3 (1) forms the sandwich cation [{P(py)3}2Fe](2+) (...
