Here we describe modified syntheses of o-acetylbenzoic acids and o-acetylphenylacetic acids by Heck palladium-catalysed arylation of n-butyl vinyl ether with o-iodobenzoic acids or with o-iodophenylacetic acids, respectively. General syntheses of ben

A novel intramolecular palladium-mediated arylation approach to benzo[b]fluoren-11-ones has been investigated. This approach involves the novel oxidation of the key starting 2-(2′-bromobenzyl)naphthols to 2-(2′-bromobenzyl)-1,4-naphthoquinones, f
