Ethyl thiourea

V-Ethyl thiourea [625-53-6] M 104.2, m 110 . Crystd from EtOH, MeOH or ether. 

This preparation is carried out in an aprotic solvent (e.g. benzene, chloroform) with no special provision other than working in a well-ventilated fume hood to avoid ill-smelling sulfur compounds. Various ligands have proved successful phosphines, pyridines, imidazoles, tetra-m ethyl thiourea, etc. When the same reaction is carried out in the absence of the Lewis base L, a dimer 6 is obtained, which is a useful catalyst in its own right and sometimes a much more active one see Section VILA. The chemical equation for that reaction is,... 

Plant. Undergoes metabolism in plants to ethyl thiourea, ethylene thiuram disulfide, thiuram monosulfide, and sulfur (Hartley and Kidd, 1987).
