Combined solution-phase, solid-phase and phase-interface anion binding and extraction studies by a simple tripodal thiourea
In 1H NMR spectra of complexes of thioureas
and heterocyclic thiones becomes less intense upon coordination and shifted down field by 0.11 ~ 0.62 ppm from their positions in free ligands.

In the first step, substituted thioureas
which were planned to use as substrates in the principal reactions, were prepared by the reaction of substituted phenyl isothiocyanate with substituted hetaryl amines.

Other chemicals used in this study included methanol, HNO3, KBr, KSCN, (NH2)2CS, Thiourea
and NaOH were of analytical grade from E.Merck.
The collected data from the frontier molecular orbitals (HOMO-LUMO) analysis of thioureas
2a and 2b are recorded in Table 3 and illustrated in Figure 2.

Although lead is occasionally used for curing chloroprenes, the use of thioureas
in this polymer group is still extensive.
