✦ Synopsis

In order to find a new efficient catalyst for the aromatic hydroxylation reaction, dissolution of several metals (Cu, Fe, Cr, Pb and Sn) into aqueous acid solutions containing benzoic acid was studied. In all systems, three isomers of monohydroxybenzoic acid and some of dihydroxy compounds were detected upon metal dissolution. Above all, the system of Sn in sulfuric acid is particularly promising as a candidate for a new catalyst system.

Singly charged metal cations do not normally activate the p-ring in monoaromatic ligands. Here pyridine complexes of six dipositive metal cations (Ca, Mg, Mn, Fe, Co, and Cu) are probed using collisional dissociation. Except for Cu, species with one-three ligands (depending on the metal) exhibit two
