Selectivity of C−H versus C−F Bond Oxygenation by Homo- and Heterometallic Fe4, Fe3Mn, and Mn4 Clusters #chempaperaday 312

I follow Agapie group's work very closely and I am a big fan of their papers. Here they report a series of clusters and found out that there is some preference for C-F vs. C-H bond oxygenation and it depends on the metal (Mn vs Fe).

Transition metal carbonyl clusters in biology: A futile or niche research area? #chempaperaday 310

Here is something that you don't see very often. For several reasons (summary in the paper), people avoid carbonyl clusters for biological applications or their use in bioinorganic chemistry. But they have been used for some applications. Rare but they are out there. I believe they will be more common in the future. These are (from the paper):

protein structural characterization, in hormone labelling, in carbonyl metallo-immunoassay (CMIA), as carbon monoxide releasing molecules (CORM) and, finally, as antiproliferative (antitumor) agents.

Nice review paper.
