Efficient photocatalytic selective nitro-reduction and C-H bond oxidation over ultrathin sheet mediated CdS flowers

We report here a visible light driven selective nitro-reduction and oxidation of saturated sp3 C-H bonds using ultrathin (0.8 nm) sheet mediated uniform CdS flowers as catalyst under a household 40 W CFL lamp and molecular oxygen as oxidant. Th

ORGANIC ELECTROLUMINESCENT MATERIALS AND DEVICES

A compound that includes a ligand LA of Formula I, Formula II, or Formula III, and the ligand LA is coordinated to a metal M. Ring A is a 5-membered, or 6-membered, aromatic ring, and Ring B a 5-membered, or 6-membered, carboxylic or heterocyclic ring. Y1, Y2, and Y3 are independently selected from the group consisting of C, N, and B, and forms an aromatic BN ring; wherein one of Y1, Y2, and Y3 is C, one of Y1, Y2, and Y3 is N, and one of Y1, Y2, and Y3 is B, and the B and N are adjacent ring atoms; and Z1 and Z2 are independently selected from the group consisting of C and N. The compounds can be used as phosphorescent dopant emitters in OLEDs. An OLED that includes an organic layer that includes a compound with a ligand LA of Formula I, Formula II, or Formula III, and a consumer product that includes the OLED.

Encapsulation of Pd(II) into superparamagnetic nanoparticles grafted with EDTA and their catalytic activity towards reduction of nitroarenes and Suzuki-Miyaura coupling

A robust, safe and magnetically recoverable palladium catalyst was synthesized by anchoring Pd(II) onto ethylenediaminetetraacetic acid-coated Fe3O4 (Fe3O4@EDTA) magnetic nanoparticles. The Fe3O4 magnetic nanoparticle-supported Pd(II)-EDTA complex catalyst thus obtained was characterized using scanning and transmission electron microscopies, thermogravimetric analysis, vibrating sample magnetometry, X-ray diffraction, and inductively coupled plasma atomic emission and Fourier transform infrared spectroscopies. Fe3O4@EDTA-Pd(II) was screened for the Suzuki reaction and reduction of nitro compounds in water. The Pd content of the catalyst was measured to be 0.28 mmol Pd g-1. In addition, the Fe3O4@EDTA-Pd catalyst can be easily separated and recovered with an external permanent magnet. The anchored solid catalyst can be recycled efficiently and reused five times with only a very slight loss of catalytic activity.

Selective reduction of nitro-compounds to primary amines by nickel-catalyzed hydrosilylative reduction

Ni(acac)2 and PMHS were found to be an excellent catalytic system for the chemoselective transfer hydrogenation of nitro-compounds to primary amines. Under mild conditions a series of nitro-compounds containing a variety of sensitive functional groups including aldehydes, esters, cyano, and nitrine were reduced to their corresponding amines in good to excellent yields with no byproduct.

Total synthesis of capsaicin analogues from lignin-derived compounds by combined heterogeneous metal, organocatalytic and enzymatic cascades in one pot

The total synthesis of capsaicin analogues was performed in one pot, starting from compounds that can be derived from lignin. Heterogeneous palladium nanoparticles were used to oxidise alcohols to aldehydes, which were further converted to amines by an enzyme cascade system, including an amine transaminase. It was shown that the palladium catalyst and the enzyme cascade system could be successfully combined in the same pot for conversion of alcohols to amines without any purification of intermediates. The intermediate vanillylamine, prepared with the enzyme cascade system, could be further converted to capsaicin analogues without any purification using either fatty acids and a lipase, or Schotten-Baumann conditions, in the same pot. An aldol compound (a simple lignin model) could also be used as starting material for the synthesis of capsaicin analogues. Using L-alanine as organocatalyst, vanillin could be obtained by a retro-aldol reaction. This could be combined with the enzyme cascade system to convert the aldol compound to vanillylamine in a one-step one-pot reaction.

A new stable modified borohydride reagent. Efficient reduction of different functional groups with sulfurated barium borohydride [Ba(BH2S3)2] in dry THF

Barium and strontium sulfurated borohydrides, Ba(BH2S3)2,Sr(BH2S3) 2 the two newly introduced modified borohydride agents, are prepared from NaBH2S3 by metathesis reaction with BaCl2 and SrCl2 in good yields. Ba(BH2S3)2 is more stable and more reactive than Sr(BH2S3)2. The reducing ability of Ba(BH2S3)2 for the reduction of aldehydes, ketones, α,β-unsaturated carbonyl compounds, azides, nitro compounds, and cleavage of epoxides in dry THF is described.
