Schiff bases from the thiosemicarbazones family with variable N4 substituents are known to show enhanced growth inhibitory properties. In view of these facts and as a part of our continuous interest in cationic Schiff bases, we have developed several Schiff base ligands from (3-formyl-4-hydroxyphenyl)methyltriphenylphosphonium (T) in present study. The compounds were characterized by various spectroscopic...
Four thiosemicarbazones ligands, H 3 T(1), H 3 M(2), H 3 E(3) and H 3 P(4) have been prepared with good yield by refluxing 2,4-dihydroxybenzaldehyde with N(4)-substituted thiosemicarbazide in ethanol (H 3 T(1)=2,4-dihydroxybenzaldehyde thiosemicarbazone; H 3 M(2)=2,4-dihydroxybenzaldehyde 4-methylthiosemicarbazone; H 3 E(3)=2,4-dihydroxybenzaldehyde...
