Synthesis of pentacarbonyliron
Hi, has anyone successfully synthesized pentacarbonyliron in the lab? I have obtained the procedure from a text but some details are omitted - such as
the time required to store the suspension under nitrogen.

Have an idea for a new version of the prep substituting for iron powder nanoscale iron which appears to have commercial application (for example, see
http://www.sciencedirect.com/science/article/pii/S0021951714... ) which you may be able to purchase. To quote from Wikipedia https://en.m.wikipedia.org/wiki/Nanoscale_iron_particles :
"Nanoscale iron particles are sub-micrometer particles of iron metal. They are highly reactive because of their large surface area. In the presence of
oxygen and water, they rapidly oxidize to form free iron ions. They are widely used in medical and laboratory applications and have also been studied
for remediation of industrial sites contaminated with chlorinated organic compounds."
My supposition is that their high reactivity could be demonstrated also with CO. So, no 12 hours of vigorous stirring (try 12 minutes,..seconds!!? ).

Pentacarbonyliron... that's an interesting substance  I've thought about
experimenting with it before, but I'm usually reluctant to play with toxic substances unless I know for sure that they will work. Carbonyl nickel is
somewhat easier to make. Please let us know if you carry out any procedures with metal carbonyl compounds
