Ethylenethiuram monosulfide

Plants. Extensively metabolized, forming ethylenethiourea, ethylenethiuram monosulfide, ethylenethiuram disulfide, and sulfur as transitory intermediates. Terminal metabolites are natural products, especially those derived from glycine... 

Ethylenethiuram monosulfide can be prepared with good yield directly from the aqueous solution of nabam by mild oxidation. In addition to the monomer, products of various degrees of polymerisation are formed (41) and sulfur... 

Ethylenethiuram monosulfide can be formed also via isothiocyanate (Kaars Sijpesteijn and van der Kerk, 1954), although oxidation plays an essential role in the reaction according to Vonk (1975). 

However, inconsistencies arose in connection with this stmcture and other workers suggested other stmctures (Pluijgers et al., 1971 Benson et al., 1972). Finally, the stmcture of ethylenethiuram monosulfide has been verified on the basis of spectral data and the fact that with carbon disulfide the compound gives an adduct. This proved to be 5,6-dihydro-3H-imidazo [2,l-c]-l,2,4-dithiazole-3-thion (DIDT, 43) (Vonk, 1975).
