The first synthesis of 18-crown-6 was reported by Pedersen in his first full paper on erowns . The method used was potassium r-butoxide catalyzed cyclization of hexa-ethlyene glycol monochloride in 1,2-dimethox ye thane, as shown in Eq. (3.7), below. Unfortunately, the yield by this approach was only 1.8%. ... 

The reaction of 2H-nonatluoro-2-methylpropane with iodine monochloride in sulfolane in the presence of potassium fluoride produces 2-chlorononafluoro-2-methylpropane in 92% yield at 50% conversion [2d]. 

Compound A (C4H10) gives two different monochlorides on photochemical chlorination. Treatment of either of these monochlorides with potassium tm-butoxide in dimethyl sulfoxide gives the same alkene B (C4Hg) as the only product. What are the structures of compound A, the two monochlorides, and alkene B ... 

Compound A (CgHi4) gives three different monochlorides on photochemical chlorination. One of these monochlorides is inert to E2 elimination. The other two monochlorides yield the same alkene B (CgHi2) on being heated with potassium tert-butoxide in tert-butyl alcohol. Identify compound A, the three monochlorides, and alkene B.

The metallocene dichloride of zirconium and hafnium 20b and 20c were also prepared and underwent reduction with potassium to give monomeric metallocene monochloride complexes 21b and 21c (Eq. 8) [39b]. The structure of the zirconocene complex 21 b in the crystal showed a conformation which suggests a less steric strain as compared to 21a due to zirconium s larger atomic size. As a consequence of the coordinative unsaturation an unusually short Zr —Cl bond length was found. 

Redox titrants (mainly in acetic acid) are bromine, iodine monochloride, chlorine dioxide, iodine (for Karl Fischer reagent based on a methanolic solution of iodine and S02 with pyridine, and the alternatives, methyl-Cellosolve instead of methanol, or sodium acetate instead of pyridine (see pp. 204-205), and other oxidants, mostly compounds of metals of high valency such as potassium permanganate, chromic acid, lead(IV) or mercury(II) acetate or cerium(IV) salts reductants include sodium dithionate, pyrocatechol and oxalic acid, and compounds of metals at low valency such as iron(II) perchlorate, tin(II) chloride, vanadyl acetate, arsenic(IV) or titanium(III) chloride and chromium(II) chloride. 

The oxidation-reduction methods with potassium iodate invariably based on the formation of iodine monochloride (ICl) in a medium of strong hydrochloric acid solution. 

Theory The iodine monochloride method described earlier employing standard potassium iodate is the basis for the official assay of potassium iodide. Vigorous shaking is a prime requirement, as the end-point is approached in this assay, because of the fact that both iodine and iodate in different phases attribute a heterogeneous medium. However, the reaction involving the oxidation of KI by iodate may be designated as shown below ...

Again the Sandmeyer reaction is frequently used to convert amino- to halo-isoquinolines. The diazonium salt of 5-amino-8-isoquinolinol (14) on treatment with potassium iodide and iodine gives the 5-iodophenol (15). Iodination of the hydrochloride of (15) with iodine monochloride in ethanol gives (16 Scheme 9) (66JMC46). 

The residual double bonds of poly(methyl acrylate) have been determined by bromination [9,27]. Bromination is accomplished through the addition of potassium bromide to potassium bromate in acidic medium [9]. Styrene-butadiene copolymers contain residual double bonds. The butadiene content of the copolymer has been determined by an iodine monochloride titration procedure [9],...

The water forces thefat/oil into the cyclohexane and the excess iodine monochloride moves into the water, where it is converted to I2 and can be titrated with the water-soluble sodium thiosulfate. Potassium iodide solution acts to convert the excess iodine monochloride to free iodine (blue) which can be titrated to a colorless end point with sodium thiosulfate. Soluble starch aids in being able to see the free iodine and getting a repeatable end point. The normality of the sodium thiosulfate solution used is generally ft 1N however, this may change depending on the level of iodine monochloride that is to be titrated. Ideally any titration should use between 5 and 50 ml (1 buret volume) of solution—titrations outside of this range can produce unreliable data.
