Water soluble (η6-arene) ruthenium(II) complexes incorporating marine derived bioligand: Synthesis, spectral and structural studies
摘要:
A series of water soluble compounds of general formula [{(eta(6)-arene)Ru(HMP) Cl}], [eta(6)-arene = eta(6)-cymene (1), eta(6)-HMB (2), eta(6)-C6H6 (3); HMP = 5-hydroxy-2-(hydroxymethyl)-4-pyrone] have been prepared by the reaction of [{(eta(6)-arene) RuCl2}(2)] with HMP. The complexes 1 and 2 react with NaN3 to give in excellent yield tetra-azido complexes [{(eta(6)-arene) Ru(mu N-3)N-3}(2)] (arene = cymene 4, HMB = 5) but similar reaction of complex 3 with NaN3 yielded di-azdo complex [{(eta(6)-C6H6)Ru(mu N-3)Cl}(2)] (6). Reaction of [{(eta(6)-arene)Ru(mu N-3)Cl}(2)] with HMP in the presence of NaOMe resulted in the formation of azido complex [{(eta(6)-arene)Ru(HMP)N-3}]. Mono and dinuclear complexes [{(eta(6)-arene)Ru(HMP)(L-1)}](+) and [{(eta(6)-arene)Ru(HMP)}(2)(mu L-2)](2+) were also prepared by the reaction of complexes 1 and 2 with the appropriate ligand, L-1 or L-2 in the presence of AgBF4 (L-1 = PyCN, DMAP; L-2 = 4,4'-bipy, pyrazine). The complexes are characterized on the basis of spectroscopic data and molecular structures of three representative compounds have been determined by single crystal X-ray diffraction study.
