observed during a Friedel–Craftsacylation/demethylation cascade. In contrast to this cascade, oxygen-containing acylating reagents do not undergo the demethylation step. By the methodology elaborated here, an access is provided to important intermediates for the total synthesis of seminaphthorhodafluor (SNARF) dyes. High selectivity is observed during a Friedel–Craftsacylation/demethylation cascade
Phenylalkylketone mit halogeniertem Alkyl, die bisher überwiegend durch Fries'sche Verschiebung von Phenolestern dargestellt worden sind, lassen sich einstufig in hoher Ausbeute durch BF3‐Kondensation von Phenolen mit Halogenfettsäuren synthetisieren.
