Three tris-bidentate cyclometalated ruthenium complexes with a di(p-anisyl)amino [5(PF6)], di(p-tolyl)amino [6(PF6)], or di(p-chlorophenyl)amino [7(PF6)] substituent on the cyclometalating phenyl ring have been prepared, where the amine nitrogen is in the meta position to the cyclometalated site (bridged through the phen-1,3-diyl unit). The structure of 6(PF6) has been confirmed by single-crystal X-ray diffraction analysis. Two consecutive redox waves are evident at +0.48 and +0.87 V versus Ag/AgCl for 5(PF6), +0.51 and +1.02 V for 6(PF 6), and +0.53 and +1.18 V for 7(PF6), respectively. The first wave is assigned to the Ru(II/III) process, and the second wave is attributed to the N(0/+) process. After one-electron oxidation using SbCl 5, these complexes display distinct absorptions in the near-infrared region, which are assigned to the nitrogen-to-ruthenium intervalence charge-transfer (ICVT) transitions. The energies of the IVCT transitions vary linearly versus the potential splitting of the Ru(II/III) and N(0/+) process. The charge-transfer direction in these complexes is reversed with respect to a previously reported ruthenium-amine system where the amine nitrogen is in the para position to the cyclometalated site (bridged through the phen-1,4-diyl unit).

Aims: Total twenty-nine [1,2,4]triazolo[4,3-a]pyrazine derivatives were designed and synthesized. Method: The target compounds, especially 4aa, showed potent activity to inhibit c-Met both in an enzyme assay and a cellular assay. The comprehensive screening for the inhibition of 60 different kinases revealed that 4aa could selectively inhibit c-Met while had no effect on other kinases, indicating 4aa is an excellent c-Met selective inhibitor. Result: The flow cytometry studies found that 4aa had a similar behavior to the positive control SGX-523 in terms of causing the tumor cell apoptosis and blocking cell-cycle progression. More importantly, 4aa showed much better pharmacokinetic properties than SGX-523. Altogether, the findings suggested the target compounds may be potential anti-tumor drug candidates.

The reaction of 1,1′-bis(diphenylphosphino)ferrocene (dppf) with a mixture of [MnRe(CO)10], MeOH and Me3NO afforded the complexes fac-[MnH(CO)3(eta2-dppf)] and [Re2(mu-OMe)2(mu-dppf) (CO)6]. In the one-pot reaction of [Re2(CO)10] with Me3NO, MeOH and dppf, the major mononuclear Re species isolated was the CO2-inserted complex fac-[Re{OC(O)OMe}(CO)3(eta2-dppf)], the crystal structure of which was determined. The coordination sphere of the rhenium atom is roughly octahedral, consisting of an oxygen atom from the methyl carbonate ligand, two phosphorus atoms from a chelating dppf ligand, and three carbon atoms from a facial arrangement of three terminally bonded carbonyls. Analogous Me3NO-mediated methoxylation reactions involving [Os3(CO)12] were also investigated. With a [Me3NO]:[Os3(CO)12] ratio of 2:1, the major product is [Os3(CO)10(mu-H)(mu-Ome)]. With three molar equivalents of Me3NO, significant quantities of [Os3(CO)10(mu-OMe)2] are also obtained. (C) 2000 Elsevier Science Ltd.

X-Ray photoelectron spectra of M(CO)n(eta1-dppf) (n = 5, M = Cr, 1, MO, 2, w, 3; n = 4, M = Fe, 4), (OC)4Fe(mu-dppf)Mo(CO)5, 5, (OC)5M(mu-dppf)M(CO)5 (M = Cr, 6, Mo, 2, W, 8) and 1,1′-bis(diphenylphosphino)ferrocene (dppf), 9, suggested that the technique can be diagnostic for pendant and coordinated phosphines, and, in heterometallic cases, be used to differentiate phosphines bound to different metals.The resolution of the P(2p) bands permits a measurement of the relative binding energies for chemically distinct phosphorus sites in the same complex thus eliminating complications in calibration as well as sample charging problems normally associated with X-ray photoelectron spectroscopy in comparative studies.
