• compounds [4][5][6]. For example, they can act as potential antitumor agents [7][8], wood preservatives, agrochemical fungicides and biocides [9][10], as well as catalysts [11]. The organotin(IV) complexes with phosphorus-based ligands bearing the P(E) group (E = O, S, or Se) are especially important

• . Comparing the phosphorus chemical shift, δ(31P), of compounds 1–4 demonstrates that it is the most deshielded atom in 4 (containing three N-phenylpiperazinyl substituents on the P atom with δ(31P) = 17.33 ppm). The 31P NMR of complexes 1–3, each containing identical phosphoric triamide ligands, show that

• the phosphorus atom is at the most upfield region in 1 with M = SnCl2(CH3)2. Further, the δ(31P) shifts downfield from 1 to 3. The complexes 1 and 4 both contain SnCl2Me2, and they differ in the phosphoric triamide ligands. The 31P NMR reveals that the phosphorus atom in 1 appears at a much more

• -disubstituted hydrazine phosphorus-containing dendrimers of the fourth generation (G4) [37]. Each dendrimer had 96 peripheral charged groups, which were either all cationic or all anionic in nature (G4(+) = G4(NH+Et2Cl−)96, Mw = 32.3 kDa; G4(−) = G4(CHCOO−Na+)96, Mw = 36 kDa). The mass of these molecules is

The metal–oxygen–phosphorus (M–O–P) interaction plays an important role for surface functionalization of imogolite nanotubes.

• . Conclusion In this work, the basic character of hydrotalcite oxides (M2+/Al3+) is reported for the first time to be essential for MP degradation. The resulting compounds are (p-NP) and other inorganic (sulfur and phosphorus containing compounds etc.) substances. The degradation of MP with hydrotalcite oxides
