General Description

Dibromo(1,5-cyclooctadiene)palladium(II) is a chemical compound that is composed of the metal palladium in its +2 oxidation state, along with two bromine atoms and a 1,5-cyclooctadiene ligand. It is commonly used as a catalyst in organic synthesis reactions, particularly in cross-coupling reactions to form carbon-carbon bonds. DibroMo(1,5-cyclooctadiene)palladiuM(II), 99% is typically sold at a purity of 99%, meaning that it contains at least 99% of the desired compound with minimal impurities. Its high purity makes it suitable for use in research and industrial applications where precise and reliable results are required.

Check Digit Verification of cas no

The CAS Registry Mumber 12145-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,4 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12145-47:
(7*1)+(6*2)+(5*1)+(4*4)+(3*5)+(2*4)+(1*7)=70
70 % 10 = 0
So 12145-47-0 is a valid CAS Registry Number.

Highly Selective Colorimetric and Luminescence Response of a Square-Planar Platinum(II) Terpyridyl Complex to Aqueous TcO4

Chatterjee, Sayandev,Norton, Amie E.,Edwards, Matthew K.,Peterson, James M.,Taylor, Stephen D.,Bryan, Samuel A.,Andersen, Amity,Govind, Niranjan,Albrecht-Schmitt, Thomas E.,Connick, William B.,Levitskaia, Tatiana G.

Molecular recognition of an aqueous pertechnetate (TcO4-) anion is fundamentally challenging partly due to the charge-diffuse nature of this anion, which hampers design of new technologies for its separation and detection. To address this gap, simple salts of transition metal complexes that undergo a distinct spectroscopic change upon exposure to aqueous anions were explored. The Pt(II) complex [Pt(tpy)Br]SbF6 (tpy = 2,2′;6′,2″-terpyridine) undergoes a dramatic color change and intense luminescence response upon TcO4- uptake due to concomitant enhancement of Pt···Pt interactions. The spectroscopic response was highly selective and quantitative for aqueous TcO4- among other competing anions. Complementary Raman spectroscopy and microscopy techniques, structural determination, and theoretical methods were employed to elucidate the mechanism of this response at the molecular level.

On the mechanistic behavior of highly efficient palladium-tetraphosphine catalytic systems for cross-coupling reactions: First spectroscopic and electrochemical studies of oxidative addition on Pd(0)/multidentate ferrocenylpolyphosphine complexes

Evrard,Lucas,Mugnier,Meunier,Hierso

, p. 2643 - 2653 (2009/02/02)

Electrochemical studies carried out in conjunction with 31P NMR spectroscopy on the palladium(II)/ palladium(O) halogeno complexes of the tetraphosphine 1,1′,2,2′-tetrakis(diphenylphosphino)-4,4′-di- tert-butylferrocene, termed Fc(P4)tBu, are reported. Fc(P4)1Bu was chosen with regard to its good performances in pallado-catalyzed cross-coupling reactions, which resulted in catalytic turnover numbers (TONs) up to 1 000 000 [Organometallics 2003, 22, 4490-4499]. The complexes [PdX2(Fc(P)4tBu}] (X = Cl, Br, I) are described with their X-ray molecular characterization in the solid state and multinuclear NMR in solution. The electrochemical behavior of Fc(P 4)tBu and [PdX2{Fc(P)4 tBu}] complexes was investigated by cyclic voltammetry and electrolysis: a formulation of the corresponding electro-generated Pd 0 species formed is proposed on the basis of their NMR characterization. The oxidative addition reaction of phenyl iodide on these zerovalent palladium/ferrocenyltetraphosphine complexes was also studied by combining electrochemistry and 31P NMR. The Pd(II) species that result from phenyl iodide oxidative addition are described, and their rate of formation under standard conditions is given; the halogeno phenyl products obtained are identified and characterized. These results are discussed in light of the knowledge existing for more classical systems combining Pd(II) halides or zerovalent palladium with n monodentate tertiary phosphines (n = 2-4). In this respect, me system using Fc(P4)tBu is relevant since its four triarylphosphine groups (Ph2PCp) are formally similar to a 4-fold excess of the triarylphosphine triphenylphosphine (PPh3) as ligand. However, the phosphorus atoms of the tetraphosphine ligand present a mutual spatial proximity that is absent in monophosphines, due to their implantation on the ferrocene platform. Therefore, the possible effects of multidentarity are discussed. Finally, the importance of palladium anionic species is confirmed in this study, and the rate value of Ph-I oxidative addition (130 ± 10 ms) on Pd(0) confirmed both the good reactivity and the enhanced stability provided to palladium species by the ferrocenyltet- raphosphine ligand.
