- MgBr2 supported on Fe3O4@SiO2?~?urea nanoparticle: An efficient catalyst for ortho-formylation of phenols and oxidation of benzylic alcohols
-
Urea was successfully immobilized on the surface of chloropropyl-modified Fe3O4@SiO2 core–shell magnetic nanoparticles, then supported by MgBr2 and acts as a unique catalyst for oxidation of benzylic alcohols to aldehydes and ketones, and ortho-formylation of phenols to salicylaldehydes. The prepared catalyst was characterized by FT-IR, transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, dispersive X-ray spectroscopy, CHN and TGA. It was found that Fe3O4@SiO2?~?urea/MgBr2 showed higher catalytic activity than homogenous MgBr2, and could be reused several times without significant loss of activity.

- PROCESS FOR PREPARING AMINOBENZOFURAN DERIVATIVES
-
This disclosure relates to a process for preparing 5-aminobenzofuran derivatives of general formula (I): in which R1 and R2 are as defined in the description, by treating a 5-N-alkylamidobenzofuran derivative of general formula (II): in which R1, R2, and R3 are as defined in the description, with a strong acid, so as to form an acid addition salt of the compound of formula (I), which salt is itself treated, if necessary, with a basic agent so as to form this compound of formula (I) in free base form.

- Para-hydroxyalkylation of hydroxylated aromatic compounds
-
Hydroxylated aromatic compounds devoid of substituents in the para-position to the hydroxyl group thereof are para-hydroxyalkylated, e.g., into optionally substituted p-hydroxymandelic acid compounds, more particularly p-hydroxymandelic acid and 3-methoxy-p-hydroxymandelic acid, by condensing same with an organic carbonyl compound in the presence of a quaternary ammonium hydroxide.

- Selective Reactions between Phenols and Formaldehyde. A Novel Route to Salicylaldehydes
-
Treatment of phenols (1) with 2 mol equiv. of paraformaldehyde in aprotic and poorly electron-donating solvents in the presence of selected metal halides coupled with suitable bases produces salicylaldehydes (3) in high yields.The route is highly selective for ortho-formylation and also specific towards monoformylation.The crucial role of added bases is emphasized.
