Catalyst palladium

Synthetic Route of 95464-05-4, 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, 95464-05-4, molcular formula is C35H32Cl4FeP2Pd, introducing its new discovery.

Selective iodination of the cyclopentadienylruthenium tricarbadecaboranyl complexes 1-(eta5-C5H5)-2-Ph-closo-1,2,3,4- RuC3B7H9 (1) and 1-(eta5-C 5(CH3)5)-2-Ph-closo-1,2,3,4-RuC 3B7H8 (2) to form their mono-iodo derivatives, 1-(eta5-C5H5)-2-Ph-6-I-closo-1,2,3,4-RuC 3B7H9 (3) and 1-(eta5-C 5(CH3)5)-2-Ph-6-I-closo-1,2,3,4-RuC 3B7H8 (4), was achieved in 90% yields by their reactions with ICl in CH2Cl2 solutions. Also isolated in trace amounts from the reaction with 2 was the di-iodo 1-(eta5- C5(CH3)5)-2-Ph-6,11-I2-closo-1,2,3, 4-RuC3B7H7, (5) complex. The sonication-promoted Sonogashira coupling reaction of 3 with terminal acetylenes catalyzed by Pd(dppf)Cl2/CuI yielded the functionalized ruthenatricarbadecaboranyl complexes 1-(eta5-C5H 5)-2-Ph-6-(Ph-C?C)-closo-1,2,3,4-RuC3B 7H8 (6), 1-(eta5-C5H 5)-2-Ph-6-[CH3CH2C(O)OCH2-C?C] -closo-1,2,3,4-RuC3B7H8 (7), 1-(eta5-C5H5)-2-Ph-6-[(eta5- C5H5)Fe(eta5-C5H 4)-C?C]-closo-1,2,3,4-RuC3B7H 8 (8) and 1-(eta5-C5H5)-2-Ph-6- [(CH3)3Si-C?C]-closo-1,2,3,4-RuC3B 7H8 (9). These reactions thus provide a versatile, systematic pathway for the syntheses of a wide variety of new types of functionalized ruthenatricarbadecaboranyl complexes.

The chromenone core is an ubiquitous group in biologically active natural products and has been extensively used in organic synthesis. Fluorine-derived compounds, including those with a trifluoromethyl group (CF 3), have shown enhanced biological activities in numerous pharmaceuticals compared with their non-fluorinated analogues. 2-Trifluoromethylchromenones can be readily functionalized at the 8- and 7-positions, providing chromenones cores of high structural complexity, which are excellent precursors for numerous trifluoromethyl heterocycles.

An iridium-catalyzed site-selective C-H borylation of 2-pyridones has been developed. The site selectivity is predominantly controlled by steric factors, and we can access C4, C5, and C6 C-H on the 2-pyridone ring by the judicious choice of ligand and solvent. Subsequent Suzuki-Miyaura cross-coupling of the borylated products also proceeds to form the corresponding arylated pyridones in good overall yields.

The first 3H-1,3-azaphospholo-pyridines 2a-c were synthesized as racemic mixtures in modest to medium yield by the reaction of N-(2-chloropyrid-3-yl)-trimethylacetimidoyl chloride 1 with RPLi2 (R = Ph, n-Bu, i-Bu), generated from RPH2 and BuLi in THF at -70 C, and studied with respect to their suitability as ligands (L) in transition metal complexes. Reactions of 2a with group 6 metal(0) pentacarbonyls led to P-coordinated LM(CO)5 complexes 3a-5a (Cr, Mo, W) and the reaction of 2c with (norbornadiene)Mo(CO)4 surprisingly to 4c. [Rh(1,5-COD)Cl]2 and 2a,b, in metal/ligand ratio 1 : 1, furnished LRh(1,5-COD)Cl complexes 6a,b with P-coordination, 6b accompanied by a minor contamination by the bis-coordinated L[Rh(COD)Cl]2 complex 7b. Reactions of 2a,b with [(allyl)PdCl]2 proceeded in THF with dismutation of N-coordinated (allyl)PdCl and formed with 2a a labile crude product [(2a){(allyl)PdCl}1.2(PdCl2)0.8]·C4H8O, with the composition close to L[Pd(allyl)Cl]PdCl2 THF (8a·THF), which converted during crystallization to 9a, whereas 2b directly formed the N,N?-PdCl2-bridged bis[LPd(allyl)chloride] complex 9b. Conversion of 2b with equimolar amounts of Pd(CH3CN)2Cl2 in THF, or Na2PdCl4 in methanol, gave rise to the dimeric P,N-bridging complex 10b. Crystal structure analyses of 6a (rac), 9b·2CDCl3 (meso), 10b·4.5THF and 10b·2D6-acetone (rac) provided detailed structural information. 10b, but more efficiently complexes formed in situ from 2a,b and Pd2(DBA)3 or Pd(OAc)2, catalysed the arylamination of 2-bromopyridine with 2,4,6-trimethylaniline.

This Communication describes studies of Ph-RF (RF = CF3 or CF2CF3) coupling at Pd complexes of general structure (PtBu3)PdII(Ph)(RF). The CF3 analogue participates in fast Ph-CF3 coupling (<5 min at 80 C). However, the formation of side products limits the yield of this transformation as well as its translation to catalysis. DFT and experimental studies suggest that the side products derive from facile alpha-fluoride elimination at the 3-coordinate PdII complex. Furthermore, they show that this undesired pathway can be circumvented by changing from a CF3 to a CF2CF3 ligand. Ultimately, the insights gained from stoichiometric studies enabled the identification of Pd(PtBu3)2 as a catalyst for the Pd-catalyzed cross-coupling of aryl bromides with TMSCF2CF3 to afford pentafluoroethylated arenes.

While there is a growing interest in harnessing synergistic effects of more than one metal in catalysis, relatively little is known beyond bimetallic systems. This report describes the straightforward access to an air-stable Pd trimer and presents unambiguous reactivity data of its privileged capability to differentiate C?I over C?Br bonds in C?C bond formations (arylation and alkylation) of polyhalogenated arenes, which typical Pd0 and PdI-PdI catalysts fail to deliver. Experimental and computational reactivity data, including the first location of a transition state for bond activation by the trimer, are presented, supporting direct trimer reactivity to be feasible.
