Thiourea isomerisation mechanism?
« on: January 13, 2011, 04:52:28 AM »
Can anyone out there give the mechanism for the thermal decomposition of thiourea into ammonium thiocyanate? Just kind of curious as to how that works exactly

I do not know with certainty, but I think the isomerization would proceed in a route similar to below:

NH2C(=S)NH2 --> NH2C(=S)NH(-) H(+) --> NH2C[--S(-)]=NH  H(+) --> (+)NH3C[--S(-)]=NH

--> NH3  S=C=NH --> NH4(+) (-)N=C=S

May you find my post a satisfactory answer
