Sulfur halides hydrogen iodide

Disulfides can be prepared by treatment of alkyl halides with disulfide ions and also indirectly by the reaction of Bunte salts (see 10-41) with acid solutions of iodide, thiocyanate ion, or thiourea, or by pyrolysis or treatment with hydrogen peroxide. Alkyl halides also give disulfides when refluxed with sulfur and NaOH, and with piperidinium tetrathiotungstate or piperidinium tetrathiomolybdate. ... [Pg.498]

Sulfuric acid is capable of oxidizing Br- to Br2 and I- to I2. Therefore, it cannot be used to prepare hydrogen bromide and hydrogen iodide. However, phosphoric acid, a nonoxidizing acid, can be used to treat bromides and iodides to form the corresponding hydrogen halides. [Pg.916]

The organo-lithium reagent can be made by exchange of Li for a halide or by deprotonation. With di-iodide 24, one iodine may be exchanged with one equivalent of BuLi and the aldehyde 25 is the product.6 The aromatic heterocycle isothiazole 26 has its most acidic hydrogen (marked) next to sulfur and it gives one aldehyde 27 in good yield.7... [Pg.95]
