Labile 1,10-phenanthroline N-oxide complexes with tin(II) and (IV) halides

Synergistic Effect of Sn and Fe in Fe–Nx Site Formation and Activity in Fe–N–C Catalyst for ORR

“…In alternative, the same synthesis also works in isopropanol. The yield was 92%, and the product was characterized by elemental analysis assuming that the final formula of the compound is Sn(phen)Cl 2 as reported by Owens et al 49 The found elemental analysis percentages seemed to confirm that assumption (C calc , 38.96%; N calc , 7.58%; H calc , 2.16%; C found , 36.83%; N found , 6.82%; H found , 2.09%). The suggested structure is shown in Figure 1a.…”

“…Therefore, SnCl 2 ·2H 2 O and 1,10-phenantroline (1:2 molar ratio in EtOH solution) were mixed. A yellow precipitate was immediately formed; the solution was filtered within 5–10 min to avoid the decomposition product to form as observed by Owens, which adopted N oxide-phenanthroline as a ligand . The product was finally washed with ice-cold ethanol and then dried overnight at 40 °C.…”

Synthesis and Characterization of 1,10-Phenanthroline-mono-N-oxides

“…Within this family of compounds, only limited information is available on 1,10-phenanthroline-1-Noxide (phenO) and its derivatives. A few metal complexes of phenO have been synthesized in solid phase since the 1970s, but the detailed characterization of these compounds is not available [18][19][20][21][22][23][24][25][26][27][28]. Recent results show that platinum(II) complexes of phenO have broad potential as oxygen atom transfer reagents because of their ability to activate the N-O bond [29].…”
