Facile synthesis of porous organic polymers for the absorption of Pd(II) ions and organic dyes

Porous organic polymers (POPs) were prepared via two-step reactions. In the first step, dialdehyde compounds were synthesized using the Suzuki-Miyaura coupling reaction, and in the second step, the dialdehyde compounds reacted with hydrazine hydrate to fo

Circularly Polarized Luminescence Designed from Molecular Orbitals: A Figure-Eight-Shaped [5]Helicene Dimer with D2Symmetry

Although many chiral molecules exhibiting circularly polarized luminescence (CPL) have been reported recently, few molecular design guidelines are known for increasing the dissymmetry factor for CPL (glum). We demonstrate that a figure-eight-shaped molecule with D2 symmetry has excellent chiroptical properties (φf = 0.08, |glum| = 1.5 × 10-2), which are attributed to the parallel arrangement of μ and m as well as a good |μ|/|m| ratio.

Porphyrin based porous organic polymers: Novel synthetic strategy and exceptionally high CO2 adsorption capacity

Iron containing porous organic polymers (Fe-POPs) have been synthesized by a facile one-pot bottom-up approach to porphyrin chemistry by an extended aromatic substitution reaction between pyrrole and aromatic dialdehydes in the presence of small amount of Fe(iii). The Fe-POPs possess very high BET surface area, large micropores and showed excellent CO2 capture (～19 wt%) at 273 K/1 bar.

Conjugated Macrocycle Polymer Nanoparticles with Alternating Pillarenes and Porphyrins as Struts and Cyclic Nodes

Conjugated macrocycle polymers (CMPs) integrated using the macrocyclic confinement effect make imposing restrictions feasible on the growth of metal nanoparticles with confined size and high dispersion. For a proof-of-concept exploration, a novel nanoscale CMP is reported, denoted as DMP[5]-TPP-CMP, comprising two representative types of macrocyclic compounds, i.e., pillararene and porphyrin, as alternating strut/node components in the skeleton. With abundant anchoring sites, CMP implanted with Pd nanoparticles (Pd@DMP[5]-TPP-CMP, Pd@CMP for short) is successfully obtained through a simple post-treatment, exhibiting remarkable catalytic activity in Suzuki–Miyaura coupling (SMC) and nitrophenol reduction. The as-prepared Pd@CMP material shows favorable performance in expediting the process of SMC with an appreciable yield even under mild conditions, as well as in facilitating the electron transfer process from borohydride to nitrophenol through metal–hydride complex to produce aminophenol with a very short transformation time of 3 min and superior apparent kinetic rate constant k app of 1.9 × 10?2 s?1, higher than most palladium supports. Significantly, this multifunctional Pd@CMP composite material not only enriches the family of CMPs, but also sheds light on the development of green catalysts with excellent stability and easy recyclability without deactivation.

Sterically hindered N-aryl/benzyl substituted piperidoimidazolin-2-ylidene palladium complexes and their catalytic activities

A series of N-aryl (2a,b) or benzyl (2c,d) substituted piperidoimidazolinium salts and their palladium complexes (3a-d) were prepared and characterized by 1H, 13C NMR, IR spectroscopy and elemental analysis. The crystal structures of 3a and 3c have been determined by X-ray crystallography. Thermogravimetric analysis (TGA) was applied to complexes (3a–d). The palladium complexes have been employed as catalyst for Suzuki-Miyaura cross coupling. The N-aryl substituted complex 3b was a highly efficient precatalyst and successfully employed in Suzuki-Miyaura cross coupling reactions of (hetero)aryl chlorides with arylboronic acids in air. In addition, the oxidative addition step of the reaction mechanism involving chlorobenzene and the catalysts 3a, 3b, 3c and 3d were computationally investigated by the DFT-ω-B97X-D method and complete agreement were obtained with the catalytic results. To measure σ-donating and π-acceptor properties of the new ligands, the rhodium carbonyl complexes were also prepared.

Synthesis of symmetrical terphenyl derivatives by PdCl 2-catalyzed Suzuki-Miyaura reaction of dibromobenzene using 3-(diphenylphosphino)propanoic acid as a ligand

A simple and efficient catalytic system for PdCl2 catalyzing the Suzuki-Miyaura reaction of dibromobenzene and arylboronic acid has been developed by using 3-(diphenylphosphino)propanoic acid as a ligand in dimethylsulfoxide at 100 °C. Using this method, a series of symmetrical terphenyl derivatives were obtained with remarkably good yields, up to 93%.

Catalytic synthesis of Bi- and teraryls in aqueous medium with palladium(II) complexes of 2-(pyridine-2-ylmethylsulfanyl)benzoic acid

Suzuki-Miyaura coupling reactions of phenylboronic and 1,4-phenylenediboronic acid with ArBr to form bi- and teraryls have been efficiently catalyzed by the air- and moisture-insensitive complexes [PdCl2L1] [1, L1 = 2-(pyridine-2-ylmethyl)sulfanylbenzoic acid; 0.05-0.5 mol-%] and [Pd(L2-H)2] (2, L2-H = 2-pyridin-2-yl-benzo[b]thiophen-3-ol; 0.01-0.5 mol-%). The complexes were formed by the reaction of [Pd(CH3CN)2Cl2] with L1, and the catalysis proceeds in water for 1. The loading of 0.1-0.5 mol-% of Pd is very promising for the coupling reactions to form teraryls. The COOH group imparts solubility to 1 in water. Ligand L2 is formed by the unprecedented cyclization of L1 in the course of the complexation reaction. The yield of 2 increases with the reaction time (5 h: 70%; 24 h: 85%). The two complexes and L1 have been characterized by NMR spectroscopy (1H and 13C{1H}). The single-crystal structures of 1 and 2 have been solved, and the Pd-S, Pd-N, and Pd-O bond lengths are 2.269(2), 1.999(6)-2.057(2), and 1.9787(17) A?, respectively. Nanoparticles (NPs) with a narrow size distribution (ca. 3.0-5.5 nm for 80-85% of the particles) formed at the start of these reactions and appear to be important for the catalytic coupling. Poisoning experiments and a two-phase test have shown that the catalysis is largely homogeneous and involves [Pd0-PdII] processes. The bond lengths and angles calculated by DFT are consistent with the experimental ones.
