cyanide addition product 2d of 1-isopropyl-3-methyl-2-benzopyrylium salts. Depending on the other substituent in position 1, 1-cyanoisochromenes in aqueous solutions of sodiumhydroxide eliminate hydrogen cyanide 2a, b, e, undergo inter-3a, b or intra-mlecular 2c, d recyclisation, or hydrolysis of the cyano group in 2f ; reaction products include α-naphthols 7c, e, β-naphthol 7d, acylchrysenes 5a,
