Friedel-Crafts reaction of 3a with p-xylene generated a C–C bond coupling product 5a in 56% yield. Treatment of 3a with other types of nucleophiles forms C–C, C–N, and C–O bonds efficiently (Fig. 4B). Furthermore, the Kumada-coupling between 5c with Grignard reagents as the ...

ResultsIn the fragmentation of protonated cyclic indolyl α-amino esters, when the two labile hydrogens on the N8 position are successively transferred to the C3 and C4 positions, a Friedel-Crafts dealkylation reaction takes place spontaneously, with concomitant formation of an ion-neutral complex of...

The Friedel-Crafts benzylation of toluene with benzyl chloride was carried out at 45 °C over ferrous and ferric sulfates calcined in air at 700, 800, and 900 °C. The benzoylation of toluene with benzoyl chloride was also performed at 110 °C over both iron sulfates heat-treated at 500...
