Gold nitrogen containing

Although a thiol-containing ssDNA probe should interact with a gold surface preferentially through the thiol group, an interaction of the nitrogen-containing side nucleotide chains with the surface cannot be excluded. 

The experimental results presented above clearly show that there are three important controlling factors which determine the catal3d ic properties of gold supported on metal oxides for oxidation. The first is the selection of suitable metal oxide supports. In the complete oxidation (combustion) of CO and nitrogen-containing organic compounds like trimethylamine gold catalysts are... 

Gold(III) is the most common oxidation state and has a 5d configuration. It is a little harder than Au(I) and readily forms complexes with oxygen- and nitrogen-containing ligands as well as soft ligands... 

This section includes selected examples of electrochemistry of gold and silver complexes with other ligands and structural types that were not included in previous sections. We have also included a list of references divided into the following areas that can be consulted for additional information sulfur- and nitrogen-containing macrocycles , porphyrins " and clusters . 

Other nitrogen-containing compounds, such as pyridines, also adsorb on the Au(lll) surface . Electrodeposition at a positive potential ca 0.4 V) leads to formation of complete layers. 2,2 -Bipyridine forms more stable monolayers as compared to those of 4,4 -bipyridine because both nitrogen atoms of the former compound could interact with the gold surface . Aliphatic nitriles do not form well-packed monolayers on gold. The compounds with more than 10 methylene units form layers only 6-8 A thick, and contact angles of these layers are ca 90-94°, significantly lower than those expected for a well-packed alkane layer ca 114°) . ... 

The redox chemiluminescence detector (RCD) is also based on the nitric oxide-ozone reaction. However, unlike the two detectors previously described, the analytes do not contain any oxidizable nitrogen. In this case a nitrogen-containing reagent such as nitrogen dioxide or nitric acid is reduced to nitric oxide by the analyte at a heated gold surface (reaction [IV]) ... 

Nitrogen nucleophiles have also proven to be suitable nucleophiles in a series of gold-catalyzed reactions, as exemplified by the transformations shown below (Scheme 16.14) [18, 17c]. The great majority of the reactions deal with the formation of nitrogen-containing heterocycles.
