Tautomeric control of the photochemistry of 4-phenylchroman-3-one

Albert Padwa; Andrew Au

Irradiation of 4-phenylchroman-3-one in ben-zene gave 2-phenylchroman-3-one as the only photo-product; the mechanism involves β-scission and recoupling of the diradical produced through the aromatic ring to give a transient spirocyclohexadienone which gives the product by a 1,3-sigmatropic shift.
