A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 114615-82-6, Name is Tetrapropylammonium perruthenate, molecular formula is C12H28NO4Ru. In a Review，once mentioned of 114615-82-6, Computed Properties of C12H28NO4Ru

Acridine derivatives constitute a class of compounds that are being intensively studied as potential anticancer drugs. Acridines are well-known for their high cytotoxic activity; however, their clinical application is limited or even excluded because of side effects. Numerous synthetic methods are focused on the preparation of target acridine skeletons or modifications of naturally occurring compounds, such as acridone alkaloids, that exhibit promising anticancer activities. They have been examined in vitro and in vivo to test their importance for cancer treatment and to establish the mechanism of action at both the molecular and cellular level, which is necessary for the optimization of their properties so that they are suitable in chemotherapy. In this article, we review natural and synthetic acridine/acridone analogs, their application as anticancer drugs and methods for their preparation. Copyright

Reference of 301224-40-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a patent, introducing its new discovery.

A concise synthesis of spiropyrrolidines and spiropiperidines has been developed. The approach employs a ruthenium-alkylidene-catalysed cross-metathesis reaction of enantiopure N-protected allylglycine with methylenecycloalkanes. The resultant alkene intermediates can then undergo a tandem acid-catalysed cyclisation to form spiropyrrolidines. Ring expansion of the spiropyrrolidine system, via an aziridinium intermediate, grants access to the homologous spiropiperidine ring system with excellent stereoretention.

The azaborate K2[nido-NB10H11] is gained from nido-NB10H13 and K[BHEt3] in a 1:2 ratio. The anion [NB10H11](2-), which is isoelectronic with [C2B9H11](2-), reacts with [{eta6-(C6R6)RuCl2}2] (R=H, Me), [{eta5-(C5Me5)RhCl2}2], or [Ni(PPh3)2Cl2] to give the azametalla-closo-dodecaboranes MNB10H11 with M=(C6Me6)Ru (2), (C6H6)Ru (3), (C5Me5)Rh (4), and (Ph3P)2Ni (5), respectively. The azametallaborane K[Co(NB10H11)2] (6), which contains a sandwich-type coordinated Co atom, is formed from K2[NB10H11] and CoCl2. The structure of 2*CH2Cl2 was determined by X-ray diffraction. The products 2-6 can be derived from the icosahedral anion [B12H12](2-) on replacing a BH(2-) moiety by the isoelectronic nitrene NH and a BHmoiety by the isolobal metal-complex fragment M. The N atom is six-coor dinated in the cluster skeletons 2-6.

In a patent, introducing its new discovery.

Polyethylene glycols (PEGs) are non-toxic, biodegradable and sustainable organic solvents, which find a large application in the chemical and pharmaceutical industry. In this study, we present the ring-closing metathesis reaction (RCM) in PEG under microwave irradiation. Several benchmark substrates, yielding 5- to 6-membered rings featuring di- or tri-substituted olefins, were evaluated. This study demonstrated that PEGs are suitable solvent for olefin metathesis. However, depending on the substrate/catalyst couple, isomerization may occur.

Electric Literature of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

A new ruthenium(II) complex, [Ru(bpy)2(Htip)]Cl2 {where bpy = 2,2?-bipyridine and Htip = 2-(thiophen-2-yl)-1H-imidazo[4,5- f][1,10]phenanthroline}, has been synthesized and characterized by 1H NMR spectroscopy, elemental analysis, and mass spectrometry. The pH effects on UV-Vis absorption and emission spectra of the complex have been studied, and the ground- and excited-state acidity ionization constant values have been derived. The calf thymus (ct) DNA binding properties of the complex have been investigated with UV-Vis absorption and luminescence titrations, steady-state emission quenching by [Fe(CN)6]4-, DNA competitive binding with ethidium bromide, DNA melting experiments, and viscosity measurements. The molecular structures and electronic properties of [Ru(bpy)2(Htip)] 2+ and deprotonated form [Ru(bpy)2(tip)]+ have also been investigated by means of density functional theory calculations in an effort to understand the DNA binding properties. The results suggest that the complex undergo three-step successive protonation/deprotonation reactions with one of which occurring over physiological pH region, and act as a ct-DNA intercalator with an intrinsic DNA binding constant value on 105 M-1 order of magnitude that is insensitive to pH.

A facile, versatile and stereoselective synthesis of bicyclic polyhydroxylated alkaloids as castanospermine analogues is described. The synthetic route started from methyl pyranosides. The key steps involved a high-yielding expeditious one-pot tandem reaction from alkenes to N-substituted delta-lactams. The delta-lactams were stereoselectively vinylated to give the dienes, which were followed by the ring-closing metathesis to produce the cyclized products. The functional group transformations of the resulting bicyclic compounds furnished diverse polyhydroxylated alkaloids in good yields. The Royal Society of Chemistry 2010.
