Orthogonal CN Plus CC Tandem Reaction of Iodoanilines Leading to Styrylguanidines Catalyzed by Supported Palladium Nanoparticles

Two birds, one nanoparticle: A highly efficient and selective tandem reaction comprising CN and CC cross-coupling of iodoanilines to form styrylguanidines by using a recyclable, heterogeneous, supported palladium nanoparticle catalyst is reported (see scheme). A mechanistic proposal based on coordination of palladium nanoparticles to the basic N atoms of aniline and guanidine is supported by isolation of palladium complexes with aniline or guanidine.
