I. Legall et al., BRIDGED HEMILABILE ALLYLPHOSPHONATE LIGAND - SYNTHESIS AND CRYSTAL-STRUCTURE OF A NEW BINUCLEAR RHODIUM COMPLEX, Organometallics, 16(16), 1997, pp. 3579-3581
The reaction of 2 equiv of the allylphosphonate CH2=CH-CH2-P(O)(OEt)(2
) with [Rh(Cl)(CO)(2)](2) results in the formation of a new binuclear
rhodium complex with two bridged bidentate allylphosphonate ligands in
cis positions, reaction with carbon monoxide induces the lability of
the phosphonate moiety, which is reversible.
