A catalyst comprised of an imide compound having an N-substituted cyclic imide skeleton represented by the general formula I: I wherein R is a hydroxyl-protecting group. The hydroxyl-protecting group R is preferably a hydrolyzable one and examples thereof include groups derived from carboxylic acid, sulfonic acid, carbonic acid, carbamic acid, sulfuric acid, nitric acid, phosphoric acid, boric acid, and so on by the removal of a hydroxyl group. The catalyst may be comprised of a combination of the above imide compound and a metal compound. Reactions of A radical-forming compounds with B radical -scavenging compounds in the presence of the above catalyst give products of addition or substitution reaction between the compounds A and B or derivatives thereof. According to the invention, organic compounds can be prepared through addition or substitution reaction or the like under mild conditions with high selectivity in high yield.
