Abstract

INDOLE and iodine form a black complex that exhibits a strong electron spin resonance signal1. The interpretation that has been given is that indole, if complexed with a small acceptor such as iodine, may act as an especially strong electron donor due to the negative formal charge that exists on carbon 2 and 3.
