The nature of a substituent on the pyrrole ring of 3-indolecarbaldehyde plays a significant role in governing the regioselectivity of metalation.To confirm the structures of the products, various indoles carrying a carbon side chain at the 4-, 5-, 6-, or 7-position were prepared by other methods.Synthesis of 5-substituted 1-hydroxyindoles is also described.Keywords-thallation; mercuration; 4-substituted indole; 5-substituted indole; 6-substituted indole; 7-substituted indole; regioselective metalation; 3-indolecarbaldehyde; thallation-palladation; 1-hydroxyindole
