Notes:
symmetrical 3,3,3′,3′-Tetraalkyl-1,1′-alkanedioylbis(thioureas) as New Chelate LigandsThe synthesis of some new alkyl-alkanedioylbis(thioureas) (3-6) by reaction of dicarboxylic dichlorides with potassium thiocyanate and secondary amines is described. They act as bisbidentate S,O ligands toward bivalent metal ions which form stable neutral chelates (7-10) extractable with apolar solvents like CHCl3 or toluene. The chelates of palladium and platinum (9 and 10) can be separated by chromatography and selectively extracted by solvent extraction.
