rainbow, go read the paper. If you have a problem with it, I'll be glad to discuss it with you.
Now, I've found some more interesting bits regarding cyanimide. Apparently, this compound is useful both in the formation of ribose sugars (I think we mentioned this before, if not remind me to mention it) and the formation of liposomes.
http://en.wikipedia.org/wiki/Cyanamide
Cyanamide is produced by hydrolysis of calcium cyanamide, which in turn is prepared from calcium carbide via the Frank-Caro process.
CaCN2 + H2O + CO2 → CaCO3 + H2NCN
The conversion is conducted on slurries, consequently most commercial cyanamide is sold as an aqueous solution.
The main reaction exhibited by cyanamide involves additions of protic reagents. Water, hydrogen sulfide, and hydrogen selenide add to give urea, thiourea, and selenourea, respectively:
H2NCN + H2E → H2NC(E)NH2(E = O, S, Se)
http://en.wikipedia.org/wiki/Thiourea
Thioureas are used a building blocks to pyrimidine derivatives. Thus thioureas condense with β-dicarbonyl compounds.[4] The amino group on the thiourea initially condenses with a carbonyl, followed by cyclization and tautomerization. Desulfurization delivers the pyrimidine.
Again, this is just stuff found in a few seconds of searching on google and wiki. It's not like this stuff is hidden.
