1-(1,3-Benzodioxol-5-yl)butan-1-one

In the mol­ecule of the title compound, C11H12O3, the dioxole ring adopts an envelope conformation. In the crystal structure, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into chains

Methyl 5-hy­droxy-3-phenyl-1,2-oxazolidine-5-carboxyl­ate

In the title compound, C11H13NO4, the isoxazolidine ring has an envelope conformation with the O atom as the flap. In the crystal, mol­ecules are liked via N—H⋯O and bifurcated O—H⋯(O,N) hydrogen bonds forming chains propagating along [010]. There are also C—H⋯O inter­actions present

2-Cyano-N,N-dimethyl­acetamide

In the crystal structure of the title compound, C5H8N2O, mol­ecules are linked by weak C—H⋯O hydrogen bonds, forming a three-dimensional network

Chlorido[6-phenyl-4-(p-tol­yl)-2,2′-bipyridyl-κ2 N,N′]platinum(II)

The asymmetric unit of the title compound, [Pt(C23H17N2)Cl], contains two independent mol­ecules with distinct dihedral angles between the central pyridyl and methylbenzene rings [7.77 (2) and 24.07 (2)°]. Short inter­molecular distances [3.582 (6) and 3.600 (6) Å] between the outer pyridine and the PtNC3 and PtN2C2 rings, respectively, indicate the existence of π–π inter­actions, which link the mol­ecules into stacks along the a axis. The crystal structure is further stabilized by weak C—H⋯π inter­actions

para-Selective C-H amidation of simple arenes with nitriles

A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred. Both steric and electronic effects are utilized to control the selectivity, resulting in only para-selective amidation products. The readily available nitriles as amidation reagents instead of amides makes the synthesis of N-arylamides more accessible

3,5-Bis(adamantan-1-yl)-1-meth­oxy­benzene

In title compound, C27H36O, all cyclo­hexane rings within the adamantyl groups adopt chair conformations. There are no obvious inter­molecular hydrogen bonds in the structure, so that van der Waals attractions stabilize the crystal

Graphene-Based Nanostructures in Electrocatalytic Oxygen Reduction

Application of graphene-type materials in electrocatalysis is a topic of growing scientific and technological interest. A tremendous amount of research has been carried out in the field of oxygen electroreduction, particularly with respect to potential applications in the fuel cell research also with use of graphene-type catalytic components. This work addresses fundamental aspects and potential applications of graphene structures in the oxygen reduction electrocatalysis. Special attention will be paid to creation of catalytically active sites by using non-metallic heteroatoms as dopants, formation of hierarchical nanostructured electrocatalysts, their long-term stability, and application as supports for dispersed metals (activating interactions)

(4R*,5R*)-Diethyl 2-(4-nitro­phen­yl)-1,3-dioxolane-4,5-dicarboxyl­ate

In the title compound, C15H17NO8, the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 6.4 (3) Å]. The five-membered ring has a twist conformation. In the crystal, C—H⋯O inter­actions link the mol­ecules into a helical chain propagating along [010]
