The electrophile in a Friedel-Crafts acylation reaction is an acyl cation (also referred to as an acylium ion) Acyl cations are stabilized by resonance The acyl cation derived from propanoyl chloride is represented by the two resonance forms... [Pg.484]

The electrophilic site of an acyl cation is its acyl carbon An electrostatic poten tial map of the acyl cation from propanoyl chloride (Figure 12 8) illustrates nicely the concentration of positive charge at the acyl carbon as shown by the blue color The mechanism of the reaction between this cation and benzene is analogous to that of other electrophilic reagents (Figure 12 9)... [Pg.484]

Trichloromethyl chloroformate has proven effective in the preparation of N-carboxy-a-amino acid anhydrides from amino acids, and various compounds having isocyanate, acid chloride, and chloroformate groups.For example, trichloromethyl chloroformate may be used instead of phosgene in the preparation of 2-tert-butoxycarbonyloxyimino-2-phenylacetonitrile. The use of this reagent is illustrated here by the synthesis of 3-isocyanato-propanoyl chloride from 3-aminopropanoic acid hydrochloride. [Pg.235]

Alternatively, the imide-acid chloride is reacted with methanol to give the imide ester which, after borohydride reduction and triethylsilane/trifluoroacetic acid treatment, furnishes the bicyclic lactam 6 as a racemate. The latter is acylated with either propanoyl chloride or 3-phcnylpropanoyl chloride and the resulting amides 7 deprotonated and alkylated with (bro-momethyljbenzene or iodomethane, respectively, to give the major alkylation products 8 with d.r. >98 2 and in 65% yield3. [Pg.908]

Anhydrous potassium fluoride displaces both the halogen atoms in 3-bromo-3,3-difluoro-propanoyl chloride (5) with fluorines at room temperature to give the acid fluoride 6 in 66% yield.30... [Pg.554]

Propanoyl chloride is unusual in that over potassium tetrafluorocobaltate(III)somechloro-fluoro derivatives are formed,88 e.g. ethyl 2-chloro-2-fluoropropanoate. Chlorination during fluorination is known with other substrates (Section 25.1.1.6.). [Pg.667]
