Abstract
Abstract Condensation of N,N′-diaminoguanidine hydrochloride with two equivalents of salicylaldehyde, 5-chlorosalicylaldehyde and 3,5-dibromosalicylaldehyde in ethanol afforded corresponding guanidinium derivatives functionalized with O,N-bidentate Schiff bases (2-HO-ArCH NNH)2C NH·HCl (Ar = C6H4, L1H·HCl; Ar = 5-ClC6H3, L2H·HCl; Ar = 3,5-Br2C6H2, L3H·HCl). Reactions of [RuHCl(CO)(PPh3)3] with one equivalent of L1H·HCl, L2H·HCl, and L3H·HCl in the presence of excess triethylamine (Et3N) in refluxing tetrahydrofuran gave the neutral ruthenium(II) complexes of the type [RuH(CO){κ2-N,N-(2-HO-ArCH NN)2CNH2}(PPh3)2] (Ar = C6H4, 1; Ar = 5-ClC6H3, 2; Ar = 3,5-Br2C6H2, 3) accordingly. X-ray crystal structure determinations are reported for complexes 1–3.
