diazonium salts as catalysts to catalyze reductive aminations of carbonyls and the synthesis of bis (3-indolyl)methane derivatives. The catalytic system showed good tolerance to substituents in the substrate in these two reactions. The separation yields of reductive aminations range from moderate to excellent. The separation yield of the reaction for synthesizing bis(3-indolyl)methane derivatives ranges
