The rhodium(III)-catalyzed C−H bond activation and vinylene transfer of enaminones with vinylene carbonate have been proposed for the synthesis of substituted 1-hydroxy-2-naphthaldehydes in 49–84% yields. Several preliminary mechanistic studies and hydroxyl-directed derivatization reactions of 1-hydroxy-2-naphthaldehydes were also performed. This method offers an alternative approach for the synthesis
