Involving the reaction of di-acetoxybenzoyl chloride with a Grignard reagent in the presence of a catalyst containing iron, a process for the preparation of the acyl benzene is provided. Acyl benzene are very useful intermediates for the multi-step process for the preparation of resveratrol....
Figure 1: Application of 1,2,3-Trimethylbenzene In a dry reaction flask, add equimolar amounts of 1,2,3-Trimethylbenzene and the corresponding ω-azidoalkyl acid chloride to dry dichloromethane (25 mL), then stir the reaction mixture at room temperature for 10 minutes. Slowly add 0.1 molar...
The same product is obtained through acylation with an ahydride as with a acid chloride...you get acetophenone or methyl-phenyl-ketone in your case: benzene-C(=O)-CH3 and acetic acid as a byproduct...the AlCl3 is not used up in the reaction ...
The acyl group in the product can be reduced using a zinc-mercury amalgam and HCl to produce an alkylbenzene. This reaction is called a Clemmensen reduction. This circumvents the rearrangement of primary alkyl groups that occurs in the Friedel-Crafts alkylation reaction. For example, acylation ...
Which one of the following is type of acylation reaction? The mechanism of this reaction iselectrophilic aromatic substitution. Acyl halides and acid anhydrides of carboxylic acids are also commonly used acylating agents. ... All react with amines to form amides and alcohols to form esters by nu...
PRECAUTIONS FOR "CARCINOGENS": Carcinogens that are alkylating, arylating or acylating agents per se can be destroyed by reaction with appropriate nucleophiles, such as water, hydroxyl ions, ammonia, thiols & thiosulfate. The reactivity of various alkylating agents varies greatly ... & is also ...
The reaction of diphenylcyclopropenone with R1N=C(R2)X (2) (R1, R2=alkyl, aryl, X=MeO, EtO, MeS, or Me2N) gave 2-pyrrolin-4-one (3) in good yield.The less reactive carboximidothioate (2, R1=4-MeC6H4, R2=Ph, X=MeS) yielded isomeric 3-pyrrolin-2-one together with 3. ...
In the presence of GaCl3, silylethyne reacts electrophilically with aromatic hydrocarbons to give β-silylstylenes (Scheme 148). The reaction is believed to proceed via a formation of an electrophilic silylethyne–GaCl3 complex, aromatic substitution, and protonolysis of the resulting vinylgallium...
0.17 ml of benzoyl chloride is added and the mixture is then stirred for 24 hours at ambient temperature. The reaction mixture is extracted with ethyl acetate and then the organic phases are combined and dried over magnesium sulphate. The residue is chromatographed on silica gel (8/2 heptane/...
