Aromatic reactions with

In their reactions with suitable nucleophiles, such as tt-aromatics or heteroatom donor nucleophiles, the readily polarizable linear acylium ions shift a Tt-electron pair to oxygen, bending the ions and developing an empty p-orbital at the carbocationic center. This enables the reaction with aromatics. The acetylation of benzene can be depicted as... [Pg.193]

Appaiendy a molai equivalent of catalyst (AlCl ) combines with the acyl halide, giving a 1 1 addition compound, which then acts as the active acylating agent. Reaction with aromatics gives the AlCl complex of the product ketone hberating HX ... [Pg.557]

Aromatics containing electron releasing groups such as phenols, dim ethyl am in oben 2en e and indole are formylated by 2-ethoxy-l,3-dithiolane in the presence of boron trifluoroetherate, followed by hydrolysis (114). The preformed dithiolanium tetrafluoroborate also undergoes Friedel-Crafts reaction with aromatics such as dim ethyl am in oben 2en e and indole (115), and was used to generate dithiolanium derivatives (formyl precursors) from the enoltrimethylsilyl ether derivatives (116). [Pg.559]

Side-chain anionic alkylation reactions with aromatic compounds take place when cataly2ed with strong basic catalysts, like Na—K (228). The yield is 83% when o-xylene reacts with butadiene... [Pg.347]

A novel method for preparing amino heterocycles is illustrated by the preparation of 2-amino-5-methylthiophene (159). In this approach vinyl azides act as NH2 equivalents in reaction with aromatic or heteroaromatic lithium derivatives (82TL699). A further variant for the preparation of amino heterocycles is by azide reduction the latter compounds are obtained by reaction of lithio derivatives with p- toluenesulfonyl azide and decomposition of the resulting lithium salt with tetrasodium pyrophosphate (Scheme 66) (82JOC3177). [Pg.73]

The reactivity of 1-methyl groups is further exemplified by their facile reaction with aromatic aldehydes to... [Pg.153]

Arylidene-5-oxazolones undergo a ring-opening reaction with aromatic thiols and a second mole of thiol is then incorporated to give products such as 48. ... [Pg.93]

A common method for the preparation of alkyl cyanide 2 is the treatment of corresponding alkyl halides 1 with cyanide. The corresponding reaction with aromatic substrates is called the Rosenmund-von-Braun reaction. [Pg.184]

Hexamethylphosphorous triamide general reaction with aromatic and heteroaromatic aldehydes to give diaryl ethylene oxides, 46,... [Pg.130]

Thiazolotriazines 636 (R = CO,Me) were prepared [84JCS(P1)2707] by cycloaddition of dimethyl acetylenedicarboxylate with triazine derivative 632. Derivatives of thiazolo[3,2-b][l,2,4]triazin-3,7-diones 637 have been formed (74JPR163) on reaction with aromatic aldehydes and diazonium salts to give 636 (R = Ar) and 638, respectively. Regioselective catalyzed... [Pg.117]

The /J-silyl phosphorus ylides 9 undergo highly cnantioselective addition reactions with aromatic and aliphatic aldehydes51. [Pg.144]

With the chiral methyltitanium reagents 39, modified by the bidentate ligands A-sulfonyl-norephedrine 38, a pronounced enantioselectivity is observed in reactions with aromatic aldehydes. Considerably lower enantiosclcction is obtained with aliphatic aldehydes36. [Pg.160]

Isopropoxycarbonyloxy radicals undergo facile reaction with aromatic substrates (e.g. toluene) by reversible aromatic substitution. 94 Isopropoxycarbonyloxy radicals react with S to give ring substitution (ca 1%) as well as the expected double bond addition.40 ... [Pg.128]

In addition to protons, other electrofugic leaving groups such as SO3 (i. e., anions of sulfonic acids), Cl, Br, I, C02, and others can also be displaced in azo coupling reactions with aromatic substrates. The mechanism of such substitutions is in principle the same as that of dehydrogenation (see Fischer and Zollinger, 1972). [Pg.319]

Two investigations on coupling reactions with aromatic amines to yield N- and C-coupling products have been carried out, namely the 7V-couplings with aniline (Beranek and Vecera, 1970) and with 7V-methylaniline (Beranek et al., 1972). ... [Pg.392]
