Abstract
1-Methylindoles are smoothly mercurated with substitution of the hydrogen atoms in the 3 position of the pyrrole ring. If, however, the latter is occupied, they are substituted in the 2 position. The resulting 2- or 3-chloromercuriindoles are readily converted to symmetrical diindolylmercury compounds, and the chloromercuri group is replaced by iodine and acyl groups; in the presence of palladium salts, they react with acrylic acid esters to form indolylacrylic acid esters.
