6-bromo-2-picolinaldehyde in two steps. Reaction of 2a–c with PdCl2 in toluene in the presence of triethylamine gave the CNN pincer Pd(II) complexes 3a–c in 18-28% yields. The CNN pincer Ru(II) complex 5 containing a Ru-NHR functionality could be obtained in a 71% yield by treatment of 2c with a Ru(II) precursor instead of PdCl2. Additionally, the related CNN pincer Ru(II) complex 7 containing a Ru–NH2 functionality
