HBr requires refluxing with a sulfuric acid catalyst. Benzyloxymethyl chloride, N,N-diisopropylethanamine, tetrabutylammonium iodide, in refluxing dichloromethane, 32 h. The reaction is conducted in refluxing dioxane, at which temperature, the sodium is liquid. In refluxing xylene solution InBr and In metal react to form InBr. Alternatively, it can be produced by refluxing iodine and nitric acid with benzene. An example of this would be the synthesis of porphyrins in refluxing propionic acid. POF can be made by refluxing difluorophosphoric acid with phosphorus pentoxide. The Alpine borane can be synthesized by refluxing alpha-pinene and 9-BBN in THF. KP1019 is synthesized by refluxing RuCl-3HO with HCl and ethanol. Ideally suited for laboratory-scale refluxing; indeed, the term reflux condenser often means this type specifically. It can be prepared by the direct reaction of zinc and iodine in refluxing ether. First, the circuitous refluxing of blood causes volume overload on the left ventricle. One report describes reacting a sample in refluxing HI for many hours. The Cbz--glutamine is treated with CDI in refluxing THF to yield Cbz-aminoglutarimide. Alternatively it can be prepared from InI and indium metal in refluxing xylenes.
