Nucleophiles aromatic

Aromatic nucleophilic substitution of 2- or 5-halogenotltia20les (146 and 148) by sulfinate affoiMs an alternative method of preparation of sulfones (147 and 149) (Scheme 76) (170, 354-356). [Pg.415]

The first step in this scheme is a classical aromatic nucleophilic substitution. Details of the method have been expounded (14—17). References 14 and 15 are concerned with the synthesis of the diaryl hahde intermediate whereas References 16 and 17 discuss the synthesis of the polymers, with emphasis on the polymerisation of PPSF by this route. [Pg.463]

A variation of the aromatic nucleophilic substitution process in which the leaving group is part of the entering nucleophile has been developed and is called vicarious nucleophilic aromatic substitution. [Pg.593]

Kinetic studies have shown that the enolate and phosphorus nucleophiles all react at about the same rate. This suggests that the only step directly involving the nucleophile (step 2 of the propagation sequence) occurs at essentially the diffusion-controlled rate so that there is little selectivity among the individual nucleophiles. The synthetic potential of the reaction lies in the fact that other substituents which activate the halide to substitution are not required in this reaction, in contrast to aromatic nucleophilic substitution which proceeds by an addition-elimination mechanism (see Seetion 10.5). [Pg.731]

Experimental observations indicate that electron-rich aromatic nucleophiles, such as phenoxide, add to phenyl diazonium ion in the same way as dimethylamine. [Pg.209]

C-Methylation products, o-nitrotoluene and p-nitrotoluene, were obtained when nitrobenzene was treated with dimethylsulfoxonium methylide (I)." The ratio for the ortho and para-methylation products was about 10-15 1 for the aromatic nucleophilic substitution reaction. The reaction appeared to proceed via the single-electron transfer (SET) mechanism according to ESR studies. [Pg.10]

All the reactions discussed in this review are aromatic nucleophilic substitutions in the ordinary sense. These reactions are briefiy described in the following sections with respect to their general kinetic features and mainly involve aza-activated six-membered ring systems, although a few studies of other heteroaromatic compounds are also available. [Pg.291]

It is quite reasonable to expect the bimolecular two-stage mechanism Sj Ar ) to predominate in most aromatic nucleophilic substitutions of activated substrates. However, only in rare instances is there adequate evidence to rule out the simultaneous occurrence or predominance of other mechanisms. The true significance of the alternative mechanisms in azines needs to be determined by trapping the intermediates or by applying modem separation and characterization methods to the identification of at least the major portion of the products, especially in kinetic studies. [Pg.152]

The lack of a uniform order of relative reactivity of the halogens in reactions of certain nucleophiles with nitro- and polynitro-phenyl halides led Parker and Read to propose a one-stage mechanism for some aromatic nucleophilic substitutions. An alternative explanation within the framework of the two-stage S Ar2 mechanism had been proposed earlier. A range of mechanisms has been considered in the past by Chapman, who properly points out that only in a limited number of examples is the evidence for the two-stage mechanism compelling even though the balance of evidence favors it. [Pg.155]

The synchronous bimolecular mechanism for aromatic nucleophilic substitution involves unfavorable geometry (bonds made and broken are both in the plane of the ring and backside attack is not possible) and unfavorable energetics (one high-energy step is required... [Pg.155]

The effect of solvation of transition states has been discussed in relation to aromatic nucleophilic substitution. [Pg.164]

It should be pointed out that the existence of stable structures of the intermediate-complex type (also known as a-complexes or Wheland complexes) is not of itself evidence for their being obligate intermediates in aromatic nucleophilic substitution. The lack of an element effect is suggested, but not established as in benzene derivatives (see Sections I,D,2 and II, D). The activated order of halogen reactivity F > Cl Br I has been observed in quantita-tivei36a,i37 Tables II, VII-XIII) and in many qualitative studies (see Section II, D). The reverse sequence applies to some less-activated compounds such as 3-halopyridines, but not in general.Bimolecular kinetics has been established by Chapman and others (Sections III, A and IV, A) for various reactions. [Pg.170]

The effect of a substituent on aromatic nucleophilic substitution can vary with ... [Pg.218]

In aromatic nucleophilic substitution, two general effects of substituents are (2) to alter the ground state in a direction toward or away from the transition state and (2) to withdraw electrons from or donate them to the pentadienoid anion in the transition state and... [Pg.219]
