Synthesis and spectroscopic characterization of 5-diaminomethylidene barbiturates
The reaction of amines with dithiocyclohexylidenes is a general reaction for the synthesis of diaminomethylidene barbiturates. When diamines of the type H2N-(CH2)n-NH 2 are used as nucleophiles bicyclic compounds are the major reaction products, with yields increasing as n decreases, n = 2, 3, 4. Wh...
