4-methoxybenzene-, chloro

This compound is called 1-chloro-4-methoxybenzene. Naming compounds is discussed in Section 2.4... 

The structure of the N-chlorodialkylamine markedly affects its reactivity and to a lesser extent its selectivity (Table II). Thus with 2-chloro-methoxybenzene as substrate, N-chloromorpholine is approximately 17,000 times more reactive than N-chloropiperidine and yet it is only slightly less selective for para-chlorination of methoxybenzene. For most substrates the shorter reaction times (less chance of other side reactions) of the more reactive N-chloroamines more than compensates for any small decrease in selectivity. 

Cunico and Maity published another example of palladium-catalyzed CO-free carbonylation of aryl halides [121]. Depending on the substrate, 2 mol% of either Pd(PPh3)4 or Pd(P Bu3)2 was used to catalyze the reaction of heteroaryl and aryl bromides with A,A -dimethyl-carbamoyl(trimethyl)silane (Scheme 2.10). Tertiary amides were prepared in good yields by direct carbamoylation under their conditions. Remarkably, chlorobenzene, 1-chloro -methoxybenzene, and iodoben-zene gave the desired products in 74, 78, and 60 % yields, respectively.

Iodination versus chlorination. Three distinct classes of halogenation reactions are observed with various substituted methoxybenzenes and IC1 when carried out under an identical set of conditions, i.e., exclusive iodination, exclusive chlorination, and mixed chlorination and iodination. For example, equimolar mixtures of anisole, 2,5-dimethyl-1,4-dimethoxybenzene and 1,4-dimethoxybenzene and iodine monochloride (kept in the dark) yield p-iodoanisole, chloro-2,5-dimethyl- 1,4-dimethoxybenzene, and a (4 6) mixture of chloro- and iododimethoxybenzene, respectively, in nearly quantitative yields,225 i.e.,... 

Reactions of 1,4-dimethoxynaphthalene and its 2-chloro, 2-bromo, and 2-(1,3-dioxolanyl) derivatives with BAIB/TMSX (X = C1, Br) combinations in dichloromethane result in acetoxylation, monohalogenation, or dihalogenation of the more activated ring (Scheme 26) [79]. Specific outcomes depend on the naphthalene derivative and reaction conditions. It is interesting that the 2-(1,3-dioxolanyl) derivative undergoes ipso-bromination with BAIB/TMSBr, and that this mode of reactivity was not observed with 2-(l,3-dioxolanyl)-l,4-di-methoxybenzene. These reactions are mechanistically diverse. Evidence was presented that bromination occurs after the formation of molecular bromine, and that chlorination probably follows a radical pathway involving the homo-...

However, neither copper(I) iodide nor photostimulation are absolutely necessary for the arylation of benzenetellurolate. Lithium benzenetellurolate and 1,2-bromoiodobenzene condensed in tetrahydrofuran at 20° to form 1,2-bis[phenyltelluro]benzene in 32% yield3. Sodium benzenetellurolate condensed similarly with l-chloro-2,4-dinitrobenzene at 20° in tetrahydrofuran/aqueous sodium hydroxide in the presence of a phase-transfer reagent. In this case 2,4-dinitrophenyl phenyl tellurium (m.p. 134°) was isolated in 30% yield4. Lithium methanetellurolate was arylated in tetrahydrofuran by iodobenzene5, 1,2-dibromobenzene, and l-bromo-2-methoxybenzene at 20°3.

Hunsdiecker Reactions. The Hunsdiecker reaction is the de-carboxylative halogenation of metal carhoxylate salts. The reaction of a,/3-unsaturated carboxylic acids with NCS and catalytic lithium acetate in acetonitrile-water provides the corresponding /3-halostyrenes in moderate yields under mild conditions. The reaction proceeds with a good degree of stereospecificity. For example, the reaction of 3-(4-methoxy-phenyl)-acrylic acid with NCS with a catalytic amount of lithium acetate at room temperature provides l-(2-chloro-vinyl)-4-methoxybenzene in good yield (eq 23). 3... 

Naphthol AS dyestuffs were invented as early as 1912 by Adolph Winther, August Leopold Laska and Arthur Zitscher of Hoechst AS is the abbreviation of Amid einer Saure (amide of an acid). Naphthol AS dyestuff components are distinguished from the unsubstituted 2-naphthol derivatives by their increased affinity for the dyed substrate and by higher chemical stability in the atmosphere. Nitro-, chloro-, methyl- and methoxybenzene derivatives can serve as aromatic moieties of the amide group. The coupling reaction with the diazo salt takes place in the 1-position. Examples of early important naphthol AS dyestuffs are Gries-heim Red, discovered in 1912, and Indra Red.
