While investigating Pd-catalyzed cross-coupling reactions between alkenyl halides and azides to yield vinyl azides, 1 H -1,2,3-triazoles were obtained as the main product.
Which indubitably indicate that the bismuthous sulfide can only dissolve in halogen acid except hydrofluoric acid, the mixed solution of dilute sulfuric acid and alkali halide.
As to metal halide torch with gallium iodide is special rise 403nm and 417nm wave crest, and the highest wave crest 417nm has conspicuousness and good effect to exposal Diazo material.
Silver halides are just some atoms of silver bound to atoms of any element known as a halogen, which includes things like bromine, chlorine, and iodine.
The silver ions in the exposed halide crystals, the ones with metallic silver in them, will have more reactions with the developer, creating more metallic silver in those grains.
In particular, one promising feature of metal halides is that they can be used to make new types of solar cells which are more efficient at converting sunlight into electricity than the silicon-based cells currently employed.
