Phenylseleninic anhydride reacts rapidly with indolines at 0 deg C to give, when the β-position is substituted, the corresponding indoles.When the β-position is unsubstituted β-phenylselenoindoles are formed.These are readily reduced by nickel boride to the parent indole.Tetrahydroisoquinoline is dehydrogenated with comparable ease.Phenylseleninic acid is also an efficient agent for these dehydrogenations.
