The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1569-16-0, 2-Methyl[1,8]-Naphthyridine, introducing its new discovery.

Two new palladium (II) complexes containing a 1,10-phenanthroline analogue N-heterocyclic carbene (NHC) have been synthesized. The complexes were characterized by 1H and 13C NMR spectroscopy and elemental analysis and their structures were determined by single-crystal X-ray diffraction. The NHC-palladium complexes were employed as catalysts for Suzuki-Miyaura coupling reactions of aryl chlorides with arylboronic acids in aqueous media at room temperature. The cross-coupling reactions were highly efficient with low catalysts loadings.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 15936-10-4, 2-Chloro-1,8-naphthyridine, introducing its new discovery.

A triruthenium metal string, [Ru3(npa)4(NCS) 2][PF6] (1), supported by naphthylridylamide (npa) ligands was successfully synthesized and is reported in this work. X-ray single crystal analysis shows that compound 1 exhibits a nonlinear [Ru3] 7 + backbone (? = 170.26(3)) with long Ru-Ru bond lengths (2.3554(8) A). The long Ru-Ru distances observed for 1 decrease the Ru-Ru interactions and electric conductance. Magnetic measurements indicate that compound 1 is in a S = 1/2 state. DFT calculations suggest that this unpaired electron occupies the pi* orbital which is stabilized by pi-acid NCS- ligands and thus weakening the Ru-Ru pi interaction.

A series of 7-[3-(1-aminoalkyl and 1-aminocycloalkyl)-1- pyrrolidinyl]quinolones have been prepared and their biological properties evaluated. Among them, 1-(S)-aminoalkyl derivatives exhibited potent antibacterial activities against gram-positive and gram-negative organisms. They had moderate lipophilicity and high aqueous solubility compared to their aminomethyl counterparts; e.g., the 3-(1-aminoethyl)-1-pyrrolidinyl compound (83) showed superior pharmacokinetic properties to its aminomethyl counterpart (6).
