Bismuth chloride oxide (BiClO basic bismuth chloride or bismuth oxychloride) is a tetragonal compoimd consisting of alternating sheets of O and Cl atoms with Bi atoms in between. It is generally synthesised from a basic bismuth nitrate solntion and sodium chloride or by dilution of a concentrated aqneous bismuth chloride solution (MacIntyre, 1992).

The oxides c f bismuth are basic, forming salts such as bismuth chloride, BiCl3- HoO, and bismuth nitrate, 3i(N0 )3 5H.,0. These salts when dissolved in water hydrolyze, and precipitate the corresponding bismuthvl compounds, BiOCl and Bi(OH), NO (or BiONOg-HoO). The compounds of bismuth have found little use bismuthyl nitrate and some other compounds are used to some extent in medicine. 

The action of the chlorides of these elements still further illustrates the progressive change in their chemical properties. The complete hydrolysis of the chlorides of phosphorus has already been observed. Arsenious chloride becomes hydrolyzed to a very great extent although some arsenious ions still exist in solution, as was stated above. Antimony chloride forms an oxychloride and bismuth chloride a basic chloride when these compounds are added to water. These facts indicate partial hydrolysis in both cases.

The chloride was also sold as blanc de Perle or pearl white when it was prepared by precipitation of aqneous bismutii nitrate with hydrochloric acid and blanc cTEspagm, where aqueous bismuth nitrate was mixed with brine Colour Index, 1971). Other terms apparently associated with this compound are flake white and bismuth white (qq.v.). The Colour Index identifies two white bismuth compounds used as pigments Cl 77163/Pigment White 14, which is listed as bismuth chloride oxide (BiClO), and Cl 77169/Pigment White 17, which is described as basic bismuth nitrate . 

Direct Titrations. The most convenient and simplest manner is the measured addition of a standard chelon solution to the sample solution (brought to the proper conditions of pH, buffer, etc.) until the metal ion is stoichiometrically chelated. Auxiliary complexing agents such as citrate, tartrate, or triethanolamine are added, if necessary, to prevent the precipitation of metal hydroxides or basic salts at the optimum pH for titration. Eor example, tartrate is added in the direct titration of lead. If a pH range of 9 to 10 is suitable, a buffer of ammonia and ammonium chloride is often added in relatively concentrated form, both to adjust the pH and to supply ammonia as an auxiliary complexing agent for those metal ions which form ammine complexes. A few metals, notably iron(III), bismuth, and thorium, are titrated in acid solution. 

Chlorination of bismuth or mercuric oxides results in precipitation of relatively insoluble basic chlorides, ie, BiOCl and HgO HgCl2. However, the reaction with is slow and does not produce high concentrations of HOCl (121). With HgO, the HOCl solutions may contain significant amounts of... 

The addition of isocyanates to hydroxy compoimds is inhibited by acid compounds (e.g., hydrogen chloride orp-toluenesulfonic acid) on the other hand, it can be accelerated by basic compounds (e.g., tertiary amines like triethylamine, N,hl-dimethylbenzylamine, and especially l,4-diazabicyclo[2.2.2]octane) and by certain metal salts or organometallic compounds (e.g., dibutyltin dilaurate, bismuth nitrate). These catalysts are often effective in amounts of much less than 1 wt%. 

Trivalent Compounds.—In trivalent vanadium compounds the basic character of the element is well developed, and both normal and oxy-salts of the sesquioxide V203 are well defined, e.g. vanadous sulphate, V2(S04)3, and vanadium oxymonochloride, VOC1. It has been previously mentioned that resemblances between the elements of the A and B Subdivisions of Group V. are mainly restricted to the pentavalent compounds it is of interest to note that the oxychloride has analogues in the trivalent antimony and bismuth basic chlorides, SbOCl and BiOCl. Trivalent vanadium also displays considerable analogy, however, with other trivalent transitional elements, as shown by the following —... 

The a-arylation of ketones, such as cyclohexanone, can be achieved using different methods. A convenient route by Pinhey et al.89), reacts cyclohexanone-2-carboxylic esters with aryllead triacetates in pyridine. The protection of the P-carboxylic ester prevents a,a-di- or even higher arylations in a -positions. The ester group can be removed by basic hydrolysis and mild thermal decarboxylation or by heating in wet dimethylsulfoxide with sodium chloride (120-180 °C)90). Barton et al. 91) have found a similar a-arylation route using the less electrophilic triphenylbismuth carbonate. In both cases probably the lead- or bismuth-enolates, respectively, are the first inter-...
