Recent developments in the coordination and organometallic chemistry of Kläui oxygen tripodal ligands

Anionic phosph(in)ito (“phosphoryl”) ligands: Non-classical “actor” phosphane-type ligands in coordination chemistry

“…The recent developments in the coordination and organometallic chemistry of the well-known phosphonate Kläui cobalt complexes was reviewed by Leung and co-workers [131]. These ligands represented below (Fig.…”

Syntheses, structures, and reactivity of ruthenium(II) hydride complexes containing Kläui’s oxygen tripodal ligand

“…While Ru hydride complexes of the type (L)Ru(PR 3 )(CO)H where L is a 6-electron tripodal ligand such as cyclopentadienyl [6], hydrido(trispyrazolyl)borate [7], and 1,4,7-triazacyclononane [8] are well known, analogous complexes with tridentate oxygen ligands are rare. We have a long-standing interest in metal complexes with the Kläui's oxygen tripodal ligand [( 5 -C 5 H 5 )Co{P(O)(OEt) 2 } 3 ]  (Scheme 1, denoted as L OEt  hereafter), which has been recognized as an oxygen analogue of cyclopentadienyl [9]. In a previous paper, we reported that the Ru(II) hydride compound (PPh 3 )(CO)L OEt Ru(H) (1) reacted with tosyl azide to give a tosylamido species.…”

Synthesis, Structure, and Reactivity of a Tetranuclear Cerium(IV) Oxo Cluster Supported by the Kläui Tripodal Ligand [Co(η5‐C5H5){P(O)(OEt)2}3]−

“…[11] Ti IV and Zr IV oxo and hydroxo clusters as well as aC e IV 6 Mo VI 12 O 7 cluster supported by L OEt À have been obtained by self-assembly of Ti IV ,Z r IV ,a nd Ce IV -L OEt complexes with oxyanionsi na queous solutions.
