Preparation of 1-naphthols from acetylenes and o-phthalaldehyde using low-valent tantalum and niobium

Kataoka,Miyai,Tezuka,Takai,Oshima,Utimoto

, p. 369 - 372 (2007/10/02)

Tantalum (or niobium)-alkyne complexes are produced by treatment of acetylenes with the low-valent tantalum (niobium) derived by zinc reduction of TaCl5 (NbCl5). Substituted 1-naphthols are prepared regioselectively by reaction of o-phthalaldehyde with the tantalum (or niobium)-alkyne complexes in good to excellent yield.
