A new palladium catalyst was prepared by immobilising ligand 2, 2′-dipyridylamine on the backbone of an acidic rosin polymer from gum rosin, on to which palladium(II) was bound via coordination. The catalyst at a low loading of 0.2 mol% was found to be highly effective for Suzuki-Miyaura coupling reactions of aryl halides and arylboronic acids under microwave irradiation in the presence of 1 equiv. of Na2CO3, affording excellent yields of the corresponding biaryls. Moreover, the catalyst exhibited very good recyclability over three cycles.

Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 499-40-1, C12H22O11.

Centered by a nitride ion: The oxidation of ytterbium with 2,2?-dipyridylamine in liquid ammonia at low temperatures leads to the novel compound [Yb3N(dpa)6][Yb(dpa)3], which is unique among homoleptic dipyridylamides of the rare-earth metals. The complete deprotonation of NH3 provides the first molecular nitride of a rare-earth metal with a Yb3N unit (see picture; C blue, N green, Yb silver).

The formation of 3,6-di-O-acetyl-1,2,4-O-orthoacetyl-alpha-d- glucopyranose was observed in the gold(i)-catalyzed glycosidation of peracetyl glucopyranosyl ortho-hexynylbenzoate; experiments with substrates bearing deuterium labeled 2-O-acetyl or 4-O-acetyl groups indicated that the orthoacetate was derived from the 4-O-acetyl group, which provided a direct evidence for the remote participation of the 4-O-acyl group in glycosylation.

Reference of 499-40-1. Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.

The heterotrimetallic complexes [FeMFe(dpa)4Cl2] (M=Ni (1), Pd (2), and Pt (3); dpa?=dipyridylamido) featuring two high-spin iron centers linked by Group 10 metals were synthesized and their physical properties were investigated. Oxidation of 1?3 with suitable oxidants in CH2Cl2 solution yielded the mixed-valent species [1]+/2+?[3]+/2+. The solution properties of [1]0/+/2+?[3]0/+/2+ were characterized by 1H NMR and UV/Vis/NIR spectroscopy as well as spectroelectrochemisty. The mixed-valent states of [1]+?[3]+ obtained by electrochemical or chemical oxidation are classified as class II valence delocalization. The solid-state structures of 1?3, [1]+, [3]+, and [1]2+ were determined by single-crystal X-ray diffraction analysis, exhibiting a linear metal framework with an approximate D4 symmetry. The spin states and magnetic properties were studied by using SQUID magnetometry, EPR and Moessbauer spectroscopy, and DFT calculations. Antiferromagnetic interactions between terminal high-spin iron centers are present within [1]0/+/2+?[3]0/+/2+ and the |J| values increase with the central metal ion changing from Ni to Pt. The DFT calculations reproduce the antiferromagnetic coupling and ascribe it to a sigma-type exchange pathway. The substitution of the central metal not only influences the spin?spin interactions but also the degree of electronic delocalization between the terminal iron sites along the Fe-M-Fe chains.

The copper(II) ion is surrounded by a distorted square-based arrangement of the two dpyam pyridyl N atoms at distances of 1.974 (2) and 1.995 (2) A, and by two acetate O atoms at distances of 1.965 (1) and 1.967 (1) A. The second O atom from each acetate group is involved in weak coordination in the tetragonal positions, at longer Cu-O distances of 2.482 (2) and 2.690 (2) A, completing the six-coordination. The overall geometry at the copper(II) ion is best described as distorted octahedral with elongated axial bonds.
