T. Itahara, PREPARATION OF NOVEL HETEROCYCLES BY DIMERIC ALKYLATION OF 2-THIOURACILS AND FORMATION OF COMPLEXES WITH COPPER AND SILVER IONS, Chemistry Letters, (12), 1996, pp. 1099-1100
Dimeric Alkylation of 2-thiouracils with dihalomethanes and alpha,alph
a'-dibromoxylenes gave novel heterocycles which were treated with copp
er(II) and silver(I) compounds to result in formation of complexes.
