Goldhalides are compounds of gold with the halogens. AuCl, AuBr, and AuI are all crystalline solids with a structure containing alternating linear chains:...
the corresponding goldhalides. Gold is strongly attacked by fluorine at dull-red heat to form gold(III) fluoride AuF3. Powdered gold reacts with chlorine...
an acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid by replacing a hydroxyl group (−OH) with a halide group (−X...
disproportionation. For example, gold(III) chloride to gold(I) chloride: AuCl3 → AuCl + Cl2 at 160°C Metal halides are also prepared by the neutralization...
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens. In particular...
example is Au(CN)−2, which is the soluble form of gold encountered in mining. The binary goldhalides, such as AuCl, form zigzag polymeric chains, again...
early days of photography, the nature of the invisible change in the silver halide crystals of the film's emulsion coating was unknown, so the image was said...
mineral pyrite (/ˈpaɪraɪt/ PY-ryte), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide)...
reaction which introduces of one or more halogens into a chemical compound. Halide-containing compounds are pervasive, making this type of transformation important...
those used in photography. It is far less sensitive to light than the halides. It was once called lunar caustic because silver was called luna by ancient...
important because of the importance of silver compounds, particularly halides, in gravimetric analysis. Both isotopes of silver are produced in stars...
executed by a transannular halide abstraction strategy through the reaction of the oxonium ion precursor (an organic halide) with the silver salt of the...
the true hydrogen halide. The behavior and chemical properties of the above pseudohalides are identical to that of the true halide ions. The presence...
form a carbon–carbon bond between a terminal alkyne and an aryl or vinyl halide. R1: aryl or vinyl R2: arbitrary X: I, Br, Cl or OTf The Sonogashira cross-coupling...
preparation of LAuR compounds is by reaction of a Grignard reagent with a gold(I) halide. A subsequent reaction with an organolithium R-Li forms the ate complex...
paper is called the emulsion. The most common chemistry was based on silver halide (the focus of this page) but other alternatives have also been used. The...
which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately...
form acids when mixed with water. Hydrogen fluoride is the only hydrogen halide that forms hydrogen bonds. Hydrochloric acid, hydrobromic acid, hydroiodic...
Gold monoiodide is the inorganic compound of gold and iodine with the formula AuI. It can be synthesized by dissolving gold powder in an aqueous solution...
a monochrome imaging process based on the light sensitivity of silver halides. They have been made for both contact printing and enlarging purposes by...
shown below, where a carbon-carbon single bond is formed by coupling a halide (R1-X) with an organoboron species (R2-BY2) using a palladium catalyst and...
