Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， COA of Formula: C14H8N2O4, Which mentioned a new discovery about 57709-61-2

The synthesis is described of a set of new N-heterocyclic compounds which are derivatives of 1,10-phenanthroline. The compounds are designed to be general purpose chelating agents which could function as tri-, tetra- or hexadentate ligands with transition metal ions. Fused-ring molecular components have been included in the design of the compounds so that they may function as binding agents to DNA through intercalation. This includes the synthesis of substituted derivatives of pyrazino[2,3-f][1,10]phenanthroline and dipyrido[3,2-a:2’3′-c]phenazine.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1271-19-8, molcular formula is C10Cl2Ti, introducing its new discovery. SDS of cas: 1271-19-8

Complexes <(C5H5)2MCl2> (M = Ti, Zr) react with the 2-(diphenyl-phosphino)phenol HO(C6H4)PPh2 in the presence of imidazole to give the corresponding complexes , 1 and (2: M = Ti; 3: M = Zr).Under the same experimental conditions, the bulkier ligand 2-(diphenylphosphinomethyl)-4-methylphenol HO(C6H3)(CH3)CH2PPh2 failed to react with (Ti or Zr) but with Cp2Zr(CH3)2 gives the methyl complex >, 4 and 2>, 5.Compounds 1 and 3 crystallize from CH2Cl2 solution, and their structures have been determined.The relatively short Zr-O bond distance of 1.979(7) Angstroem, and the Zr-O-C bond angle of 160.2(5) deg, in one phenoxy ligand of 3 suggest significant double bonding between Zr and O atoms.Chemical reduction of 1 with Na/Hg gives the expected cyclic P-metallated ZrIII species characterized by EPR (g = 1.976; a(31P) = 14.6 G.).Preliminary data indicate that 3 acts as a diphosphine ligand upon reaction with<2>.

Chemistry is an experimental science, Formula: C10Cl2Ti, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1271-19-8, Name is Titanocenedichloride

The ring-opening metathesis polymerization (ROMP) of norbornene (NBE) with 11 substituted titanocene dichlorides and MeLi as catalysts was studied. The substituent effect showed that the catalytic activity was generally decreased as the substituents were introduced into the Cp ring. The more bulky the substituents, the lower the activity and the bis-substituted titanocene appeared to have an even lower catalytic activity. The molecular weight of polynorbornene (PNBE) also decreased as substituents are introduced on the Cp ring. But the molecular weight distribution and cis structure content have no significant differences compared with non-substituted titanocene complex as catalyst.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C10Cl2Ti, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1271-19-8, in my other articles.

A series of seven Ru(II) complexes bearing NHC ligands have been synthesized. The electronic structures of these complexes were analysed by spectroscopic and electrochemical methods and further examined by theoretical calculations. Data show that absorption maxima are dependent on the HOMO level rather than the HOMO-LUMO gaps.
