Hexaaquaaluminum methanesulfonate crystals, [Al(H2O)6][CH3SO3]3 (1) were synthesized by a hydrothermal reaction of Al(OH)3 with methanesulfonic acid. Single-crystal diffraction determination revealed that Al3+ was coordinated by six water mols. in octahedral geometry, while the CH3SO3– anion connected with Al3+ through coordinated water mols. by hydrogen bonds. The six-coordinate environment of Al was also determined by 27Al MAS NMR measurement. TGA and FTIR spectroscopy showed that the decomposition intermediate at 265-365° was Al2(μ-OH)(CH3SO3)5 (2) and the final product was amorphous Al2O3 residue with ∼0.8% SO3 at 520-800°. A pure phase of [Al(H2O)6][CH3SO3]3 was confirmed by powder x-ray diffraction anal. Esterification of n-butyric acid with n-butanol and ketalization of cyclohexanone with glycol catalyzed by [Al(H2O)6][CH3SO3]3 and Al2(μ-OH)(CH3SO3)5, resp., proceeded in 100% yield by continuously removing the produced water. In the case of tetrahydropyranylation of n-butanol at room temperature in dichloromethane, the catalytic activity of [Al(H2O)6][CH3SO3]3 was much lower than that of Al2(μ-OH)(CH3SO3)5. Furthermore, both [Al(H2O)6][CH3SO3]3 precursor and Al2(μ-OH)(CH3SO3)5 catalysts could be recycled.
