Abstract
![]()
N-Triphos derivatives
(NP3R, R = alkyl, aryl)
and asymmetric variants (NP2RXR′, R′ = alkyl, aryl, X = OH, NR2, NRR′) are
an underexplored class of tuneable, tripodal ligands in relation to
the coordination chemistry of Re and Tc for biomedical applications.
Mixed-ligand approaches are a flexible synthetic route to obtain Tc
complexes of differing core structures and physicochemical properties.
Reaction of the NP3Ph ligand with the Re(V)
oxo precursor [ReOCl3(PPh3)2] generated
the bidentate complex [ReOCl3(κ2-NP2PhOHAr)], which possesses an unusual
AA’BB’XX’ spin system with a characteristic second-order
NMR lineshape that is sensitive to the bi- or tridentate nature of
the coordinating diphosphine unit. The use of the asymmetric NP2PhOHAr ligand resulted in the formation
of both bidentate and tridentate products depending on the presence
of base. The tridentate Re(V) complex [ReOCl2(κ3-NP2PhOAr)] has provided
the basis of a new reactive “metal-fragment” for further
functionalization in [3 + 2] mixed-ligand complexes. The synthesis
of [3 + 2] complexes with catechol-based π-donors could also
be achieved under one-pot, single-step conditions from Re(V) oxo precursors.
Analogous complexes can also be synthesized from suitable 99Tc(V) precursors, and these complexes have been shown to exhibit
highly similar structural properties through spectroscopic and chromatographic
analysis. However, a tendency for the {MVO}3+ core to undergo hydrolysis to the {MVO2}+ core has been observed both in the case of M = Re and markedly
for M = 99Tc complexes. It is likely that controlling this
pathway will be critical to the generation of further stable Tc(V)
derivatives. An N-centered tripodal heterofunctionalized
phosphine ligand
was used to generate a reactive “metal-fragment” based
on the {MVO}3+ (M = Re, 99Tc) core
for the formation of mixed-ligand [3 + 2] complexes. Characteristic
lineshapes arising from an AA’BB’XX’ spin system
are diagnostic of bidentate vs tridentate coordination modes of the
ligand.
