Reductive Silylation of the Uranyl Ion with Ph3SiOTf

“…The U–O dbm bond lengths in 1 (av. U–O = 2.25 Å) are slightly shorter than those observed for uranyl dibenzoylmethanate complexes. ,− which is consistent with the absence of uranyl character in the molecule. However, the U–O triflate distance in 1 [2.349(2) Å] is similar to those exhibited by uranyl triflate complexes. ,, Finally, the U–N and U–O acnac bond lengths in 2 are 2.380(2) and 2.153(2) Å, respectively, and are comparable to those observed for related U(V) silyloxide complexes …”

Reductive silylation of a uranyl dibenzoylmethanate complex: an example of controlled uranyl oxo ligand cleavage

“…69 UO 2 (dbm) 2 (THF) was synthesized by modifying the previously reported procedure for the preparation of UO 2 (hfac) 2 (THF) (see below). 49,70,71 All other reagents were purchased from commercial suppliers and used as received.…”

NMR spectra were recorded on a Varian UNITY INOVA 400 MHz spectrometer or a Varian UNITY INOVA 500 MHz spectrometer.…”

(Dibenzylacetone-κO)(1,3-diphenylpropane-1,3-dionato-κ2O,O′)dioxouranium(VI)

“…In a continuation of our work on uranyl bis(-diketones) with neutral donor ligands (Rajagopal et al, 2002;Alagar et al, 2003), we report here the structure of the title compound, (I), [UO 2 (DBM) 2 DBA] [DBA = (C 6 H 5 CH CH) 2 CO], to compare the observed UÐO(DBA) bond distance with the reported bond distance of UÐO(DBA) in [UO 2 (TTA) 2 DBA] (Kannan, Venugopal, Pillai, Droege, Barnes & Schlempe, 1996).…”
