Iron zirconium phosphate nanoparticles have been used as an efficient catalyst for the selective oxidation of a wide range of alcohols to their corresponding ketones or aldehydes using H 2 O 2 as an oxidizing agent without any organic solvent or additive. The steric factors associated with the substrates had a significant influence on the reaction conditions. The results showed that this method can be applied for chemoselective oxidation of benzyl alcohols in the presence of aliphatic alcohols. The catalyst used in the current study was characterized by ICP-OES, XRD, N 2 adsorption-desorption, NH 3 -TPD, Py-FTIR, SEM, and TEM.

“…It is well known that the radii of the Fe 3+ ion (0.64 Å) and the hydrated Fe 3+ ion (3.9 Å) are smaller than the basal spacing of ZP (7.5 Å) [66,67]. These results therefore provide evidence that Fe 3+ ions were inserted into the ZP interlayers and increased the basal spacing of the modified ZP during the ion exchange process [4,9,10,17]. Taken together, the above characterization data show that ZPFe had been successfully synthesized.…”

“…In contrast, the presence of electron withdrawing groups (carboxyl and nitro groups and halogens) on the phenol ring decreased the reaction rate (Table 3, entries [11][12][13][14][15]. The optimized reaction conditions were also successfully applied to obtain the acetylation of benzylic alcohols bearing either electronwithdrawing or electron-donating groups, without the formation of any by-products resulting from oxidation reactions (Table 3, entries [17][18][19][20][21][22]. In the case of deactivated aromatic rings (Table 3, entries 21 and 22), the acetylated products were obtained in much lower yields and required longer reaction times than the corresponding activated aromatic systems (Table 3, entries [18][19][20].…”

It has also been reported that ZP pos-sesses excellent selectivity towards Pb 2+ , Zn 2+ , and Fe 3+ as an ion exchanger [15][16][17]. Furthermore, ZP has been shown to exhibit antibacterial activity when loaded with Cu 2+ , Zn 2+ , or Ce 3+ [5,6,13,14].…”

In the present study, a mild, rapid, and efficient method for the protection of aldehydes with acetic anhydride (AA) in the presence of iron zirconium phosphate (ZPFe), at room temperature is reported. Selective conversion of aldehydes was observed in the presence of ketones. Under these conditions, different aldehydes bearing electron‐withdrawing and electron‐donating substituents were reacted with AA and the corresponding 1,1‐diacetates (acylals) were obtained in high to excellent yields. The steric and electronic properties of the different substrates had a significant influence on the reaction conditions. Also, the deprotection of 1,1‐diacetates has been achieved using this catalyst in water. The catalyst was characterized by several physico‐chemical techniques. It was recovered easily from the reaction mixture, regenerated, and reused at least 7 times without significant loss in catalytic activity. This protocol has the advantages of easy availability, stability, reusability of the eco‐friendly catalyst, chemoselectivity, simple experimental and work‐up procedure, solvent‐free conditions and only a stoichiometric amount of AA is needed.
