The synthesis of enantiomerically pure propargylic alcohols is possible using the same methodology 43b. Thus, addition of (—)-[(l-chloro-2-phenylethyl)sulfinyl]-4-methylbenzene (14) to propan-al led to a mixture of the diastereomers 15A/15B (d.r. 44 56) which are easily separated by column chromatography. After thermal elimination of the sulfinyl group the vinyl chlorides 16A/16B were obtained as a mixture of E- and Z-oleftns. Elimination of hydrogen chloride was carried out with three equivalents of butyllithium, leading to enantiomerically pure 1 -phenyl-1-pentyn-3-ol. 

Information about the products of a reaction can be particularly informative when one of them is quite unexpected. Thus the reaction of chloro-4-methylbenzene (p-chlorotoluene, 6) with amide ion, eNH2, in liquid ammonia (p. 173) is found to lead not only to the expected 4-methylphenylamine (p-toluidine, 7), but also to the quite unexpected 3-methylphenylamine (w-toluidine, 8), which is in fact the major product ... 

When the parent molecules connected by the azo group are different, azo is placed between the complete names of the parent molecules, substituted or unsubstituted. Locants are placed between the affix azo and the names of the molecules to which each refers. Preference is given to the more complex parent molecule for citation as the first component, e.g., 2-aminonaphthalene-l-azo-(4 -chloro-2 -methylbenzene). 

Although anthraquinone is the starting point for the preparation of many derivatives, involving substitution and replacement reactions, certain compounds are obtained directly by varying the components in the above synthesis. Thus, for example, replacement of benzene with methylbenzene (toluene) leads to the formation of 2-methylanthraquinone. A particularly important variation on the phthalic anhydride route is the synthesis of 1,4-dihydroxyanthraquinone (6.6 quinizarin) using 4-chlorophenol with sulphuric acid and boric acid as catalyst (Scheme 6.3). The absence of aluminium chloride permits hydrolysis of the chloro substituent to take place. 

There is a long history of the preparation of explosive solids or oils from interaction of diazonium salts with solutions of various sulfides and related derivatives. Such products have arisen from benzene- and toluene-diazonium salts with hydrogen, ammonium, or sodium sulfides [1,5] 2- or 3-chlorobenzene-, 4-chloro-2-methylbenzene-, 2- or 4-nitrobenzene- or 1- or 2-naphthalene-diazonium solutions with hydrogen sulfide, sodium hydrogen sulfide or sodium mono-, di- or poly-sulfides [l]-[4,7], 4-Bromobenzenediazonium solutions gave with hydrogen sulfide at -5°C a product which exploded under water at 0°C [2], and every addition of a drop of 3-chlorobenzenediazonium solution to sodium disulfide solution...

Hexachlorobenzene (perchlorobenzene) is a high-melting solid consisting of white needles and used as a seed fungicide, wood preservative, and intermediate for organic synthesis. Bromobenzene (fp, -31°C bp, 156°C) serves as a solvent and motor oil additive, as well as an intermediate for organic synthesis. Most l-chloro-2-methylbenzene is consumed in the manufacture of 1-chloroben-zotrifluoride.

A mixture of 10.3 parts of l-chloro-4-(chloromethyl)-2-nitrobenzene, 25.2 parts of l-(diphenylmethyl)piperazine and 120 parts of ethanol is stirred and refluxed for 4 h. The reaction mixture is cooled and evaporated. The residue is taken up in about 100 parts of water and the product is extracted with methylbenzene. The extract is washed with water, dried, filtered and evaporated. The residue is purified by column-chromatography over silica gel using trichloromethane as eluent. The pure fractions are collected and the eluent is evaporated. The residue is crystallized from a mixture of 2,2 -oxybispropane and hexane (1 2 by volume). The product is filtered off, washed with hexane and dried, yielding 19.6 parts of l-(4-chloro-3-nitrophenylmethyl)-4-(diphenylmethyl)piperazine melting point 101.6°C.
