Regioselective c-f bond activation of hexafluoropropylene on palladium(0): Formation of a cationic H2-perfluoroallylpalladium complex

A chemoselective C(sp2) -F or C(sp3)-F bond activation of hexafluoropropylene (HFP) was achieved by adopting the proper combination of a Lewis acid co-additive with a ligand which coordinates Pd0. The treatment of [(h2- HFP)Pd(PCy3)2] with B(C6F5)3 allowed a chemoselective C- (sp3)-F bond cleavage of HFP to give a unique cationic perfluoroallypalladium complex. In this complex, the coordination mode of the perfluoroallyl ligand was considered to be of the unique h2-fashion.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: chiral-phosphine-ligands, you can also check out more blogs about12150-46-8

Merging metallic catalysts and sonication: A periodic table overview

This account summarizes and discusses recent examples in which the combination of ultrasonic waves and metal-based reagents, including metal nanoparticles, has proven to be a useful choice in synthetic planning. Not only does sonication often enhance the activity of the metal catalyst/reagent, but it also greatly enhances the synthetic transformation that can be conducted under milder conditions relative to conventional protocols. For the sake of clarity, we have adopted a structure according to the periodic-table elements or families, distinguishing between bulk metal reagents and nanoparticles, as well as the supported variations, thus illustrating the characteristics of the method under consideration in target synthesis. The coverage focuses essentially on the last decade, although the discussion also strikes a comparative balance between the more recent advancements and past literature.

alpha-Functionalization of 2-Vinylpyridines via a Chiral Phosphine Catalyzed Enantioselective Cross Rauhut-Currier Reaction

Herein, 2-vinylpyridines as a new type of electron-poor system for the asymmetric cross Rauhut-Currier reaction are reported. 2-Vinylpyridines are chemo- and enantioselectively activated by a newly designed chiral phosphine catalyst. The new reaction provides a powerful synthetic tool for accessing structurally diverse, highly valued chiral pyridine building blocks in good yields and with high enantioselectivities. Preliminary mechanistic studies reveal that two NH protons in the catalyst are critical for the synergistic activation of the substrates and governing the stereoselectivity of this reaction.

One-Pot Halogen Dance/Negishi Coupling of Dibromothiophenes for Regiocontrolled Synthesis of Multiply Arylated Thiophenes

One-pot halogen dance/Negishi cross-coupling of readily available 2,5-dibromothiophenes is described. A lithium diisopropylamide (LDA)-mediated halogen dance reaction resulted in the formation of thermodynamically stable alpha-lithiodibromothiophenes, which were transmetalated with ZnCl2and subjected to Negishi cross-coupling to provide the corresponding arylated dibromothiophenes in one pot. The resultant beta-bromo group was much less reactive than the remaining alpha-bromo group, which was used in a one-pot double Suzuki?Miyaura cross-coupling, enabling facile synthesis of multiply arylated thiophenes.

Synthesis, Characterization, DNA Interaction Study, Antibacterial and Anticancer Activities of New Palladium(II) Phosphine Complexes

A series of palladium(II) complexes with N,N-dimethylthiourea and phosphines [tri-p-tolylphosphine (Tptp), benzyl(diphenyl)phosphine (Bdp), cyclohexyl(diphenyl)phosphine (Cdp)] were synthesized by the direct reaction of K2[(PdCl4)] with the corresponding phosphines and then with N,N-dimethylthiourea at a molar ratio of 1: 2: 2. The general formula of these complexes is [Pd(L1)2(L2)2]Cl2, where L1 = N,N-dimethylthiourea (Dmtu), L2 = Tptp, Bdp, Cdp. The complexes were characterized by elemental analyses, multinuclear NMR (1H, 13C, 31P), and FT-IR. The complex with cyclohexyl(diphenyl)phosphine was also characterized by single crystal X-ray analysis. The spectral and crystallographic data suggest monodentate coordination of dimethylthiourea through the sulfur atom and of the phosphine ligand through the phosphorus atom and distorted square planar environment of palladium(II). The synthesized complexes have been screened for DNAbinding, antibacterial, cytotoxic, and antitumor activities. The complexes show interaction with DNA via intercalative mode. The complexes show good activity against both gram positive and gram negative bacteria as compared to that of a standard drug, Imipenem. Their antitumor activity against MCF7 tumor cell line was found to be comparable with doxorubicin. MTT assay was used to investigate the cytotoxicity of the studied compounds having activity order: 3 > 2 > 1.

[Pd(acac)(L)2][BF4] (L?=?morpholine, diethylamine, dibutylamine, dioctylamine): Synthesis, structure and their catalytic activity

Cationic acetylacetonate bis(secondary amine) palladium (II) complexes were synthesized by nitrile substitution of [Pd(acac)(MeCN)2][BF4] with L (L?=?morpholine, diethylamine, dibutylamine, dioctylamine) which yielded [Pd(acac)(L)2][BF4] as a mononuclear species with chelating acac ligand. An X-ray diffraction, NMR, IR and DFT study of [Pd(acac){morpholine}2][BF4] establishes the presence of hydrogen bonding between the morpholine ligand and [BF4]? anion. Crystallographic defects in the crystal and presence of pseudocrystalline structure in solution of [Pd(acac){morpholine}2][BF4] were assumed to explain IR spectra features. Preliminary investigations into the polymerization of norbornene, dimerization of styrene, and telomerization of 1,3-butadiene with diethylamine were performed.
