Site-Specific Methylation of Coordinated 1,2,4-Triazoles: A Novel Route to Sterically Hindered Ru(bpy)2 Complexes
摘要:
A site-specific methylation of 1,2,4-triazolate rings in ruthenium(II) complexes Using OMe3+BF4- is reported. Interestingly methylation takes place preferentially at the most sterically hindered nitrogen atom of the coordinated triazole ring.
