SDS of cas: 1452-77-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Picolinamide, is researched, Molecular C6H6N2O, CAS is 1452-77-3, about Bis-heteroleptic ruthenium(II) complex with 2-picolinamide: Synthesis, crystal structures, and spectroscopic study for anion recognition using the amide group. Author is Toyama, Mari; Fujii, Yudai; Endo, Mika.

Cis-[Ru(bpy)2(OH2)2](OTf)2 (1·(OTf)2; OTf- = CF3SO3-) was reacted with 2-picolinamide (H2pia) in EtOH to form bis-heteroleptic complex [Ru(bpy)2(H2pia)]X2 (2·X2; X- = OTf- or Cl-). Crystal structures of 2·X2 revealed that H2pia was coordinated to Ru(II) through N of pyridyl group and O of amide group to form the N,O-coordination, and acted as a neutral ligand. Bond distances around the amide group and 1H NMR study for 22+ suggested that π-electron on the carbonyl group was delocalized to the whole amide group. Adding F- to the acetonitrile solution of 2·(OTf)2 changed the red solution to dark-red due to the transportation of π-electron on the amide group by the bound F- to the amide H. Absorption and 1H NMR spectroscopies revealed that the NH2 of 22+ undergoes selective two-step adduct reaction with F-: the H close to pyridyl group of H2pia first formed a 1:1 adduct (mono-F-adduct-22+), followed by the other H forming the 1:2 adduct (di-F-adduct-22+). Adding excess Li(OTf) to these F-adduct-22+ solutions changed the dark-red solution back to red, suggesting that the adducted F- was removed by Li+ to form 22+ and LiF.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Mass spectrometry of platinum(II) complexes. Comparison of cis and trans isomers. Fragmentation and rearrangement pathways.Synthetic Route of C10H10Cl2N2Pt.

The mass spectra of 8 pairs of cis and trans isomers of PtL2X2 (L=NH3, pyridine PEt3, or PPh3; X=Cl, Br, or I) are presented and discussed. Two chelates, Pt(bipy)Cl2 and Pt(dpm)Cl2(dpm=di-α-pyridylmethane), are also included. The most significant results are: (1) parent ions can be observed for almost all these relatively involatile coordination compounds; (2) most ligand fragmentations and rearrangements occur with ligand-metal bonds intact; (3) some rearrangements appear to involve the metal; (4) cis and trans isomers of phosphine complexes give different fragmentation patterns; (5) spectra of chelates differ considerably from the spectra of analogous nonchelates; (6) in Pt(NH3)2Cl2 and Pt(py)2Cl2, little or no difference is observed in the spectra of cis and trans isomers after electron impact. Therefore, excitation to a tetrahedral state may take place.
