The reactivity of a reduced heterobimetallic Co(-I)/Zr(IV) complex, ((t)BuNC)Co((i)Pr2PNMes)3Zr(THF) (), with a series of azido and diazo reagents is explored to demonstrate the feasibility of facilitating two-electron redox processes at a formally d(0) Zr(iv) center using the appended Co fragment exclusively as an electron-reservoir. Addition of mesityl or adamantyl azide to affords the terminal ((t)BuNC)Co((i)Pr2PNMes)3Zr[triple bond, length as m-dash]NMes () and bridging ((t)BuNC)Co((i)Pr2PNMes)2(μ-NAd)Zr((i)Pr2PNMes) () Co(I)/Zr(IV) imido products, respectively. Similarly, diphenyldiazomethane reacts with to afford the terminal Ph2CN2(2-)-bound product ((t)BuNC)Co((i)Pr2PNMes)3Zr[triple bond, length as m-dash]N-N[double bond, length as m-dash]CPh2 () via a two-electron oxidation of the Co center. Thermolysis of results in a structural rearrangement to the diazomethane-bridged isomer ((t)BuNC)Co((i)Pr2PNMes)2(μ-N2CPh2)Zr((i)Pr2PNMes) (). In contrast, treatment of with 0.5 equivalents of the conjugated diazo reagent ethyl diazoacetate affords a tetranuclear Zr(IV)/Co(0) complex, ((t)BuNC)Co((i)Pr2PNMes)3Zr(μ2-κ(1)-O-η(2)-N,N-OC(OEt)CHN2)Zr(MesNP(i)Pr2)3Co(CN(t)Bu) (), bridged through enolate and η(2)-bound diazo functionalities.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 June 2016.
All research outputs
#24,088,415
of 34,360,889 outputs
Outputs from Dalton Transactions: An International Journal of Inorganic Chemistry
#11,237
of 24,747 outputs
Outputs of similar age
#292,418
of 446,137 outputs
Outputs of similar age from Dalton Transactions: An International Journal of Inorganic Chemistry
#610
of 2,104 outputs
Altmetric has tracked 34,360,889 research outputs across all sources so far. This one is in the 28th percentile – i.e., 28% of other outputs scored the same or lower than it.
So far Altmetric has tracked 24,747 research outputs from this source. They receive a mean Attention Score of 2.4. This one has gotten more attention than average, scoring higher than 51% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,137 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2,104 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
