sequential method for the synthesis of indanones is advantageous, as it limits even more electron rich external arenes only to the Friedel–Crafts alkylation. This is not possible in previous reports wherein both cinnamic acid ester and the external arenes are treated together in the presence of an acid, wherein the relatively more reactive arene is preferred to facilitate the acylationstep.

donors or alcoholic solvents led to α-carbonylradicals. The utility of the α-carbonylradicals was demonstrated in intramolecular tandemcyclization and in the synthesis of 9-phenanthrols and their analogues. The mechanistic experiments suggested that quenching of the reactive benzotriazolyl radical by the alcohol was accompanied by the formation of an α-hydroxy radical that mediated hydrogen atom transfer
