Copper photoredox catalysts for polymerization upon near UV or visible light: Structure/reactivity/efficiency relationships and use in LED projector 3D printing resins

Copper complexes (CuCs) bearing pyridine-pyrazole ligands are synthesized and evaluated as new photoredox catalysts/photoinitiators in combination with an iodonium salt (Iod) for the free radical polymerization of (meth)acrylates and the cationic polymerization of epoxides upon visible light exposure using a Light Emitting Diode (LED)@405 nm. The structure/reactivity/efficiency relationships for the copper complexes are studied as well as the chemical mechanisms involved. The different substituents on the pyrazole moiety of the ligand allow tuning of the oxidation potential and the visible light absorbance of the complexes and to optimize the performance of the polymerization photoredox catalysts. The use of a novel additive (CARET) in a three-component system (CuC/Iod/CARET) highly improves the performance. Finally, the high performances of the Cu(i) complexes for the development of new 3D printing resins using an LED projector are demonstrated. Currently, LED projector printing is really advantageous in 3D printing i.e. this technology projects the profile of an entire layer at one time.

A new heterobimetallic palladium-[60]fullerene complex with bidentate bis-1,1?-[P]2-ferrocene ligand

A new heterobimetallic palladium-[60]fullerene complex with ferrocene bis-phosphine ligand was prepared using alternative paths: either via addition reaction of Pd2(dba)3·C6H6 (dba=dibenzylidenacetone) in the presence of 1,1?-bis(diphenylphosphino)ferrocene (dppf) to C60, or via electrochemical activation of C60 to generate C602- anions, which then react with PdCl2 and dppf to yield the target complex. The obtained (eta2-C60)Pd(dppf) complex was characterized by 1H- and 31P-{1H}-NMR and electronic spectroscopy as well as electrochemically.

Palladium Nanoparticles?Polypyrrole Composite as Effective Catalyst for Fluoroalkylation of Alkenes

Abstract: Palladium nanoparticles?polypyrrole composite (Pd/PPy) catalyzes the addition of perfluoroalkyl halides to olefins to produce a variety of products with good yields. An effective fluoroalkylation technique tested with various olefins, fluoroalkyl halides and Pd/PPy was developed. The reaction proceeds highly efficient under mild phosphine-free reaction conditions with different substrates, easy catalyst recycling and provides a general and straightforward access to fluoroalkylated products. Furthermore, we were able to control whether the addition of perfluoroalkyl occurs with various monomer (fluoroalkylated alkene or alkane with RF and OH moieties) or dimer formation (under electrochemical conditions).

Polymerization of conjugated dienes and olefins promoted by cobalt complexes supported by phosphine oxide ligands

Four cobalt complexes supported by phosphine oxide (P=O) donors (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine oxide) cobalt dichloride (Co1), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine oxide) cobalt bromide (Co2), N, N’-(pyridine-2,6-diyl)bis(P,P-di-tert-butylphosphinic amide) cobalt dichloride (Co3) and N, N’-(pyridine-2,6-diyl)bis(P,P-di-tert-butylphosphinic amide) cobalt dichloride (Co4) were prepared and characterized. Their catalyses performances in polymerization of isoprene, butadiene, myrcene as well as MMA and styrene were examined. In combination with AlEt2Cl, Co1 and Co2 are able to convert isoprene to polyisoprene, whereas the activities of Co3 and Co4 are much low. The resultant polyisoprene are mixture of cis-1,4 and 3,4 isomers, whose ratio are not significantly affected by the type of catalysts and polymerization conditions. Isoprene was found to be more active than myrcene, and butadiene in the case of Co1/AlEt2Cl, suggestive of compromised sterical and electronic effect from the alkyl group at 2-positon of monomers. The Co1/AlEt2Cl system is also moderately active in polymerizations of methyl methacrylate and styrene. Therefore, the current catalysts provided dual polymerization reactivities towards conjugated dienes and olefins that are rare in transition metals catalyzed coordinative polymerization.

Heteroleptic Cu(I) complexes with aromatic diimines and phosphines: Synthesis, structure, photophysical properties and THz time domain spectroscopy

Nine novel copper(I) complexes with diphosphine and diimine ligands, namely [Cu(dpq)(xantphos)]BF4 (1), [Cu(dpq)(xantphos)]I (2), [Cu(dpq)(dppp)]BF4 (3), [Cu(dppz)(dppp)]BF4 (4), [Cu(dppz)(dppp)]I (5), [Cu(dppz)(pop)]I (6), [Cu(dpq)(pop)]I (7), [Cu(dpq)(pop)]Br (8), [Cu(dpq)(pop)]SCN (9) (dpq = pyrazino[2,3-f][1,10]phenanthroline, dppz = dipyrido[3,2-a:2?,3?-c]phenazine, xantphos = 9,9-dimethyl-4,5-bis(diphenylphosphanyl)xanthene, dppp = 1,3-bis(diphenylphosphino)propane, pop = 1,1?-[(Oxydi-2,1-phenylene)]bis[1,1-diphenylphosphine]), were characterized by single crystal X-ray diffraction, IR, elemental analysis, 1H NMR, 31P NMR, fluorescence spectra and terahertz time domain spectroscopy (THz-TDS). These nine complexes were synthesized by the reactions of copper salts, diimine ligands and various of P-donor ligands through one-pot method. Single crystal X-ray diffraction reveals that complex 9 is of a simple mono-nuclear structure while complexes 6 and 7 are of dimer structures. For complex 8, hydrogen bonds and C?H?pi interactions lead to the formation of a 1D infinite chain structure. Interestingly, complexes 1?5 show novel 2D or 3D network structures through C?H?pi interactions. In addition, complexes 1?3 and 6?9 exhibit interesting fluorescence in the solid state at room temperature. Among the nine complexes, complex 1 shows the highest quantum yield up to 37% and the lifetime of 1 is 6.0 mus. The terahertz (THz) time-domain spectra of these complexes were also studied.

Dicarbonylruthenium(II) complexes of diphosphine ligands and their catalytic activity

The hexa-coordinated chelate complexes of the type [Ru(CO)2Cl2(P-P)](1a,b) [where P-P = 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene(a) and [bis(2-diphenylphosphinophenyl)ether(b)] have been synthesized by reacting the polymeric precursor [Ru(CO)2Cl2]n with the ligands in 1:1 molar ratio. The complexes 1a,b are characterized by elemental analyses, Mass, IR and NMR spectroscopy together with the single crystal X-ray structure determination of 1a. The compound 1a crystallizes in a monoclinic system with space group C2/c showing a slightly distorted octahedral geometry around the Ru centre. The complexes 1a and 1b are thermally stable up to 300 C and exhibit high catalytic activity in transfer hydrogenation of aldehyde and ketones to corresponding alcohols. The complexes 1a and 1b show much higher catalytic activity for the hydrogenation of aldehyde than ketones. In general, the catalytic efficiency of 1b is higher compared with 1a.

Synthesis, structures and photophysical properties of copper(I) 2-(2-benzimidazolyl)-6-methylpyridine complexes with different diphosphine ligands

A series of new Cu(I) 2-(2-benzimidazolyl)-6-methylpyridine (Hbmp) complexes containing five different diphosphine auxiliary ligands have been synthesized and well characterized. It is revealed that all Cu(I) atoms display distorted N2P2tetrahedral geometries with distinct P?Cu?P bond angles regulated by diverse diphosphine ancillary ligands, in which Hbmp serves as a charge-neutral chelating ligand without the deprotonation of the benzimidazolyl-NH while the diphosphine ligand adopts a bridging or chelating coordination mode. It is demonstrated that all these Cu(I) complexes show a relatively weak low-energy absorption in solution and exhibit good luminescence properties in solution and solid states at room temperature, which are more markedly influenced by the P?Cu?P bond angle.

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.Quality Control of: (Oxybis(2,1-phenylene))bis(diphenylphosphine), you can also check out more blogs about166330-10-5
