Perfluoroaryl Azide Staudinger Reaction: A Fast and Bioorthogonal Reaction

We report a fast Staudinger reaction between perfluoroaryl azides (PFAAs) and aryl phosphines, which occurs readily under ambient conditions. A rate constant as high as 18 m?1 s?1 was obtained between methyl 4-azido-2,3,5,6-tetrafluorobenzoate and methyl 2-(diphenylphosphanyl)benzoate in CD3CN/D2O. Furthermore, the iminophosphorane product was stable toward hydrolysis and aza-phosphonium ylide reactions. This PFAA Staudinger reaction proved to be an excellent bioothorgonal reaction. PFAA-derivatized mannosamine and galactosamine were successfully transformed into cell-surface glycans and efficiently labeled with phosphine-derivatized fluorophore-conjugated bovine serum albumin.

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.

Aggregation-induced emission behavior of a pincer platinum(II) complex bearing a poly(ethylene oxide) chain in aqueous solution

An amphiphilic pincer platinum(II) complex with a poly(ethylene oxide) (PEO) chain exhibited aggregation-induced emission (AIE) because of micelle formation in water. The AIE activity was enhanced by the addition of 1,3,5-benzenetricarboxylic acid, which induced micelle formation through hydrogen-bonding interactions with the PEO chain.

Synthesis of new mixed-ligands Tc complexes containing monodentate phosphine and isothiocyanato ligands: Crystal structures of complexes Tc(P(C3H7)3)2(NCS)4, Tc(P(CH3)2Ph)4(NCS)2 and Tc(P(OCH3)Ph2)4(NCS)2·1/2CH2Cl2

Three mixed-ligand neutral technetium complexes containing monodentate phosphine and isothiocyanato ligands have been synthesized and studied by crystallographic methods. In the Tc(IV) compound trans-Tc(P(C3H7)3)2(NCS)4, the Tc atom is located on an inversion centre. The Tc-P bond distances are 2.519(3) A while the Tc-N bonds are 1.991(6) and 2.003(6) A. Two Tc(II) compounds containing tetrasubstituted phosphine ligands were also characterized by X-ray diffraction methods. In transTc(P(CH3)2Ph)4(NCS)2 (II), the Tc atom is located on a twofold axis. The Tc-P bond distances are 2.429(2) and 2.482(2) A while the Tc-N bonds are 2.052(6) A. In trans-Tc(P(OCH3)Ph2)4(NCS)2·1/2CH2Cl2, the Tc-P bond distances vary between 2.423(1) and 2.442(1) A, while the Tc-N bonds are 2.039(1) and 2.037(1) A. All the complexes have octahedral geometry around the Tc atom, with N-bonded isothiocyanato ligands. Important distortions of the octahedron was observed in compound II, due to the bulkiness of the four dimethylphenylphosphine ligands located in the same coordination plane. An important tetrahedral deformation of the plane containing the Tc and the four P atoms was observed. (C) 2000 Elsevier Science S.A.

Effect of phosphine ligand on the optical absorption/emission properties of platinum-containing conjugated polymers

The Sonogashira-Hagihara coupling polymerization of a d-hydroxyphenylglycine-derived diiodoarylene monomer and platinum-containing diethynylphenylene monomers with various substituents, HCC-C6H4-CC-Pt(PR3)2-CC-C6H4-CCH, 1: R = C4H9, 2: R = C8H17, 3: R = cyclohexyl, 4: R = phenyl, and 5: R = 4-methoxyphenyl, gave the corresponding polymers 1?-5? with number-average molecular weights of 4600-22000. The polymers were soluble in CHCl3, CH2Cl2, THF and DMF. CD/UV-vis spectroscopic analysis and dynamic light scattering measurements revealed that 1?-5? formed chirally regulated unimolecular structures in THF/toluene mixtures, while formed chiral aggregates in THF/MeOH mixtures. The conjugation of the polymer main chain was longer for monomers with aryl groups bonded to P compared to monomers with alkyl groups bonded to P. The relationship between the HOMO-LUMO gaps and phosphine ligands was reasonably explained by DFT calculations. The polymers exhibited photoluminescence with quantum yields ranging from 0.003% to 0.9%. The photoluminescence intensity was controlled by changing the phosphine substituents. The thermal stability of the polymers increased and the refractive index decreased as the alkyl chain length of the phosphine ligand was increased.

Synthesis of aminoboronic acid derivatives: An update on recent advances

Both alpha- and beta-aminoboronic acids and their derivatives are particularly useful as synthetic precursors, biochemical probes and drugs, although the development of novel compounds has long been hindered by the lack of synthetic options. We highlight the developments in this field, starting from the landmark Matteson homologation methodology, and moving to some elegant and convenient methods reported mainly over the last 4 years. Here, these novel and often very general methods are described and compared with each other, with their respective benefits and potential drawbacks defined. We focus on their stereoselectivity and determine whether the methods are substrate or catalyst controlled, or yield racemic mixtures.

Synthesis of new, paramagnetically modified heterocycles

Starting from readily available paramagnetic five- and six-membered ketones and pyrroline aldehyde, a range of spin labeled heterocycles such as benzazoles, pyrrole, oxazole, quinoline, benzofuran, thiadiazole have been synthesized in both ‘classical’ and Pd-catalyzed reactions. These methods were used in the synthesis of paramagnetic ligands such as oxin and porphyrin. Georg Thieme Verlag Stuttgart.

Silver(I) complexes of bis[2-(diphenylphosphino)phenyl] ether

The reaction of AgOTf in dichloromethane with bis(2-(diphenylphosphino)phenyl) ether (DPEphos) in an equimolar ratio afforded a dinuclear complex [Ag2(kappa2-P,P?-DPEphos)2(mu-OTf)2] (1), whereas the similar reaction in a 1:2 molar ratio resulted in the formation of a bis-chelating complex [Ag(kappa2-P,P?-DPEphos)2][OTf] (2). The silver(I) complex 1 was obtained as a dimer, in which two silver atoms are bridged by two triflate groups to form three adjacent eight-membered spirocyclic rings. The mixed-ligand complex [Ag(kappa2-P,P?-DPEphos)(2,2?-bpy)][OTf] (3) was obtained in the reaction of 1 in dichloromethane with 2,2?-bipyridine. The crystal structures of complexes 1-3 were determined by single crystal X-ray analyses.
