Abstract
AbstractThe iridium(III)‐catalyzed dehydrogenative coupling of salicylic acids with diarylacetylenes proceeds smoothly accompanied by decarboxylation to produce 5,6,7,8‐tetraarylnaphthalen‐1‐ols selectively. This reaction can be conducted even without addition of external oxidant. The same kind of naphthalen‐1‐ol derivative can also be synthesized predominantly by the reaction of 4‐hydroxybenzoic acid with diphenylacetylene. Some of naphthalen‐1‐ols prepared exhibits unique optical properties.magnified image
