Abstract
An efficient, ligand-free, and Pd-catalyzed method for the synthesis of imidazoisoindole imine scaffolds with satisfactory yields via C-C and C-N bond formation has been developed. The synthesized scaffolds have unique potential for selective MeOH detection from other solvents, especially EtOH. The appealing features of this transformation are phosphinic ligand-free conditions, the use of a small amount of Pd(OAc)2, and a practical procedure for the synthesis of imidazoisoindole imine scaffolds.
