Excellent! Is this done using hydrazine as a reducing agent? Please share your method. I've only done it using thermal decomposition of copper formate:

Thanks, I've been trying to do one but I have no access to a Schlenk line only a commercial standard vacuum pump.

Formaldehyde works pretty well!
I am still optimising the method a bit, but will post as soon as worked out properly.
